Mail delivery problem

Hi I have a few email accounts on my Macbook pro..all run through the default Apple mail client.
up until a week ago all was fine..now I can only receive emails on all accounts not send them..have checked smtp settings and renewed permissions but nothing sends...just the cog spinning and eventually fails the send..All accounts work fine on my iphone using the same router..
Now if I take my laptop to my mates house it all works fine!! we both use BT infinity home hub 3 routers..and yes all its settings are the same as default..
Any ideas guys??

I have experienced the same problems. I could receive but not send email through a third party email. Our ISP is BT and it would appear even though they wont admit it that they have changed some peoples settings.
I spoke with my email provider 123-reg and they asked me to check my ISP and then check the SPAMHAUS and our ISP has been Blocklisted. I called BT and they wouldnt answer why this had happened.
To cut a long story short I have had to pay BT £30 (not happy) to resolve the problem. They set my SMTP details as mail.btinternet.com and i had to authenticate this by logging into a BT/Yahoo email account that we never use., go to options then mail options then mail accounts and add details for the account your having problems with. You should then receive an email link on your third party email address.
I have actually complained to OFCOM about this as I dont believe that I should have to pay to rectify a problem that I havent caused. All BT would say is that they fixed the problem and I have to pay the £30. they wouldnt answer why I couldnt send emails prior to this fix. I asked why I now have to have the SMTP as mail.btinternet.com and again they couldnt answer this.
I hope this helps

TS3276 Internet Mail Delivery Problem

I have been getting "Internet Delivery Problem" on my email since midnight last night. All my email is coming through, accompanied by the above message, and all messages are going out. I don't see how to fix this. Any suggestions? I am on iCloud and went to Connection Doctor, and it said everything was fine!

Seems to not be system-wide. My husbands .mac account is behaving just fine.
Just curious, did anyone having problems also lose service a while back? If I understood what happened correctly, Apple had one big server center go down and I lost email for a couple of days but my husband didn't. So he's located on a different server than mine. Everyone seems randomly assigned since the outage was world-wide, and just those routed out of this one location lost service. Took them a while to acknowledge the issue, since it wasn't everyone. Curious if this is affecting the same people?

Mail delivery problems and incorrect time stamps

I'm running Server 10.4.9 and along with hosting two webpages I am hosting email for one of the domains. Whenever a message is received by an account hosted by my server, the time listed for receiving the email is incorrect. It varies from 1 to 4 hours fast or slow depending on the source of the email. It happens with both incoming and outgoing mail. If a message is sent from one account to another on my server, the time stamp is correct.
In addition to the incorrect time, I have noticed messages directed to one account being delivered to another. For example, in my own mailbox I recieve messages that were intented to go to another user mailbox on my server. I don't know if that is related to the same problem or if it is a spam issue but I figure any bit of information will be helpful.
And finally, I do not believe all mail is reaching the intended mailbox. I have junkmail and notjunkmail accounts enabled for spam and if I redirect 10 emails usually only 5 at the most will make it. I get no return errors when redirecting (ex: undeliverable)
I have checked the obvious time and date panels in OS X including the server admin and everything matches. The timezone is also correct. I type date into the terminal and that comes up correct as well. This isn't my first time configuring a server.... I've hosted mail servers with 10.2 and 10.3 in the past with no problems but this is my first time using 10.4. I'm pretty comfortable navigating through the server, but I have limited experience in terminal. (Just for FYI) Usually with enough time I can figure almost anything out, but I've run out of ideas here. Any help would be greatly appreciated. Thanks...

Where are you looking at the timestamp? On the message headers? Are you taking into account any timezone corrections on same headers? E.g. following message sent from Apple HQ to UK...
Received: from uk2mxserver3-10.uk2.net ... Sun, 15 Apr 2007 10:24:34 +0100 (BST)
Received: from bz3.apple.com ... Sun, 15 Apr 2007 10:24:31 +0100
Received: from acutil03.apple.com ... Sun, 15 Apr 2007 02:24:22 -0700 (PDT)
Otherwise you will need to post examples.

What does the mail.log show for these messages? You should be able to track them moving through the system.

OBIEE Mail Delivery Problem

Hi everyone,
I am trying to schedule an analysis to send an email in daily basis to a specific group of people. People can change according to their position in the company so the list must be dynamic. I tried to use option 'Get Recipients from the Analysis Used in the Agent Condition' in the recipients tab of schedular page. I created a different analysis just contains required email address list. Then choose its email column to get the recipients. Then run my agent, but no email is delivered. It is not working and I can not understand the reason Only mail is delivered when I write email addresses hard code such as xxx.hotmail.com etc.. What can be the problem?
Please help me.

Hi,
I found the reason but thank you for your attention again. The reason is SA System configuration changes are applied to the user profiles after login attempt. Users who do not login to the system after the configuration don't have an email address configured on their profiles.
Regards

problems receiving IMAP mail

What problem? I have no problem with mail and Mavericks, but I just upgraded my wife's 2012 MBP to Mavericks. Now she doens't get mail as frequently as before. With perferences set to check either automatically or every five minutes, she gets mail that is several hours old. She's using IMAP (@icloud.com, @me.com, or @mac.com).
Any ideas,

Mail Delivery Problems ... Out of Nowhere!

As of this morning when I send email (some not all) I get a message back saying ...
*The original message was received at Mon, 29 Nov 2010 10:05:56 -0800*
*from omta003 [127.0.0.1] ----- The following addresses had permanent fatal errors ---- (reason: 550 No such user - psmtp)*
yet the people I'm emailing are receiving the email. Does anyone know what's going on??? These are addresses that I've used before and have never seen this happen.

I called my email provider and when they sent they didn't get a responce coming back ... so the theory is that somehow within mac mail when I type in the new email address its still connecting to the old.
See she used to have one email address and now has got a new one and cancelled the old one, yet when I send to the new one it seems to send the email through but it sends a transcript back to me saying it didn't go through. I think something within mail is connecting to the old address - what can I do to insure there is no trace of that old addess? I deleted it from my address book but I see it still shows up in mail.

TS3276 problem with mail delivery

has anyone else gotten a "problem during delivery processing" message with each outgoing message? it just randomly started happening to me this morning. it says my message was sent but the reason: Error in sieve filter: Notify mailto: recipient is not a valid address
one comes from postmaster@mac and one comes from Internet Mail Delivery....

My Wife and I both have an Ipad and an iPhone, I use an iMac and my wife a MacBook Pro.
I have this problem with all my devices.
My wife has NOT got this problem.
We both use a [email protected] email acount.
Just compared the settings:
For "Incoming server" I have p03-imap.mail.me.com
My Wife has p02-imap.mail.me.com .... and has not got this problem.
I have setup a new rule for incoming mails (for the meantime):
move all incoming emails from [email protected] to trash and delete it.
Works fine for now,......until APPLE deals with the problem.

Mail delivery error with 5510 e-print. updates and connection are ok. friend has same problem.

I have checked all of the updates and connections for my new printer. As far as I can tell, I've checked everything that needs to be checked and all is good. But, I still get the Mail Delivery error when e-printing. And my friend has the same problem with her new 5510 b111a. What could possibly be the problem? Regular printing, scanning and so on work fine with my wireless connection.
This question was solved.
View Solution.

So it sounds like it may be an Issue with the provided Email Address from your internet service provider, you are sending from ,
What i would suggest as a test is to create a Email account either with g mail and or yahoo, and try to send the email to your eprint account/Email, and see if it accepts the email also, make sure you have your printer set to Accept email from all users you can do this by logging into Eprint Center and then going into these settings and selecting that option
I am an HP employee.

Problem with "Mail Delivery System" ...

I have been getting this "Mail Delivery System" notice. My colleagues responded to my e-mail and they got the same response after replying to my email. They would ask me if I got their email. I did get their email reply with no problem.
So I tested my mac.com address by emailing from my office: [email protected] to [email protected] - I even get this message. I was perplexed! I checked my Address Book. The set up is correct on both of my personal Powerbook G4 and office Mac G5. I am not sure how "[email protected]" with missing "c" for "com" had occurred.
Is there something I should check out to fix this problem. It started in early August 2007. It never happend before.
Here's the actual message:
This is the Postfix program at host fallback.us4.outblaze.com.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

If you do so, please include this problem report. You can delete your own text from the attached returned message.

Mail Delivery System email problems

After (unsuccessfully) bouncing some suspicious emails I now have 37 Mail Delivery System emails which refuse to be deleted no matter what I do. I can delete them and they go to trash but then they appear back in the inbox. For a while these emails were 'empty' as in I could not open them as there was nothing but the email title there but now they have suddenly become readable and they all have the same address which obviously could not be bounced and some have the junk sign next to them which I can't get rid of either. It is very annoying although obviously it does not affect anything other than it looks awful to have 37 emails from the same place. Incidentally I think that there are actually only 2 emails as there are only 2 different time stamps on them and I think that they have multiplied due to me deleting them so often and them reappearing again. Hope this makes sense to someone!

eventually the emails disappeared!

[Solved] postfix local mail delivery fails

Hi Guys,
on my home pc i use postfix (gmail as a smtp relay) and fetchmail for sending/receiving mails, this works very well, however sending a mail to a local user fails, I'm lost here and need your help guys.
if i send a mail like :
$>echo "Test" | mail -s "Test : local mail delivery" "andy"

# For common configuration examples, see BASIC_CONFIGURATION_README
# and STANDARD_CONFIGURATION_README. To find these documents, use
# the command "postconf html_directory readme_directory", or go to

# SOFT BOUNCE
# The soft_bounce parameter provides a limited safety net for
# testing. When soft_bounce is enabled, mail will remain queued that

# To turn off local recipient checking in the SMTP server, specify
# local_recipient_maps = (i.e. empty).
# The default setting assumes that you use the default Postfix local
# delivery agent for local delivery. You need to update the
# local_recipient_maps setting if:
# - You define $mydestination domain recipients in files other than
# /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
# For example, you define $mydestination domain recipients in
# the $virtual_mailbox_maps files.
# - You redefine the local delivery agent in master.cf.
# - You redefine the "local_transport" setting in main.cf.
# - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
# feature of the Postfix local delivery agent (see local(8)).
# Details are described in the LOCAL_RECIPIENT_README file.
# Beware: if the Postfix SMTP server runs chrooted, you probably have
# to access the passwd file via the proxymap service, in order to
# overcome chroot restrictions. The alternative, having a copy of
# the system passwd file in the chroot jail is just not practical.
# The right-hand side of the lookup tables is conveniently ignored.
# In the left-hand side, specify a bare username, an @domain.tld

# TRUST AND RELAY CONTROL

# In particular, "trusted" SMTP clients are allowed to relay mail
# through Postfix. See the smtpd_recipient_restrictions parameter
# in postconf(5).
# You can specify the list of "trusted" network addresses by hand
# or you can let Postfix do it for you (which is the default).
# By default (mynetworks_style = subnet), Postfix "trusts" SMTP
# clients in the same IP subnetworks as the local machine.
# On Linux, this does works correctly only with interfaces specified
# with the "ifconfig" command.
# Specify "mynetworks_style = class" when Postfix should "trust" SMTP
# clients in the same IP class A/B/C networks as the local machine.
# Don't do this with a dialup site - it would cause Postfix to "trust"

# Alternatively, you can specify the mynetworks list by hand, in
# which case Postfix ignores the mynetworks_style setting.
# Specify an explicit list of network/netmask patterns, where the
# mask specifies the number of bits in the network part of a host
# address.
# You can also specify the absolute pathname of a pattern file instead
# of listing the patterns here. Specify type:table for table-based lookups
# (the value on the table right-hand side is not used).

# - from "trusted" clients (IP address matches $mynetworks) to any destination,
# - from "untrusted" clients to destinations that match $relay_domains or
# subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
# In addition to the above, the Postfix SMTP server by default accepts mail
# that Postfix is final destination for:
# - destinations that match $inet_interfaces or $proxy_interfaces,
# - destinations that match $mydestination
# - destinations that match $virtual_alias_domains,
# - destinations that match $virtual_mailbox_domains.

# no relayhost is given, mail is routed directly to the destination.
# On an intranet, specify the organizational domain name. If your
# internal DNS uses no MX records, specify the name of the intranet
# gateway host instead.
# In the case of SMTP, specify a domain, host, host:port, [host]:port,

# TRANSPORT MAP
# See the discussion in the ADDRESS_REWRITING_README document.
# ALIAS DATABASE
# The alias_maps parameter specifies the list of alias databases used

# On systems with NIS, the default is to search the local alias
# database, then the NIS alias database. See aliases(5) for syntax
# details.
# If you change the alias database, run "postalias /etc/aliases" (or

I have solved it, and this was the problem (main.cf) message_size_limit = 0 i have set this to unlimited "0" so bigger mails not get rejected by postfix, the defualt value was 10240000 (~10 Mb) after finally checking the postfix log with journalctl -u postfix (because /var/log/mail.log) is not used anymore i found this line : "fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit" after setting mailbox_size_limit to unlimited "0" postfix starts to delivery local mail.

How this started:
Over the past couple of days to approx a week, I have seen a massive influx of Spam on our server. Spam coming in on random ex employee names that no longer work for the company.
Previous to the spam, I turned on "forward un-deliverable mail to" and set to me. The CEO was missing emails because people were not spelling his name correctly. I have actually been able tyo catch a lot of employee emails some important, others not.
In trying to make the mail server more secure, one of the features I tried to turn on was SMTP Client Restrictions, Which broke SMTP for my users. Obviously the error is mine and I need to do more research, but love some feedback on what needs to be set on the server and clients for SMTP client restrictions to work.
I know THE HOFF (mr hoffman) had information at some point to help users secure postfix, can anyone point me in the right direction, as well as any tips here on how to stop the influx of spam?

I am not certain what you mean by immediately removing the 192.1.1.10 and 192.1.1.11, AIX servers that I use to relay admin emails to an IT address here. Some sort of a gateway implemented on a pair of IBM boxes, I might presume.
192.1.1.0/24 is in a public address space that you don't have assigned (unless you're BBN). If that IP routing leaks out, then some folks can get cranky. Or should you eventially need to contact hosts within the address space of the "real" occupants of 192.1.1.0/24, routing won't necessarilt play nice. There may well be a static IP route here, depending on the details of the router configuration, as otherwise that IP traffic would be going to BBN and not to those servers. The Internet works because folks play by the rules, when working with IP routing and DNS services. And if your predecessor used this address space (and not the likely 192.168.0.0/16 block), I'd look around to see if there were other unusual network configuration choices.
TCP port 25 is the server-to-server mail port. That's the main connection used among mail servers. Blocking that has the effect that you've discovered.
It's the clients that can also use that port that need to be relocated off the port, as the clients don't have the reverse DNS and related tests that would allow them access to that port, with various common server security configurations.
Open TCP 587 at the firewall and ensure that this port is active at the mail server host, as a starting point. You can test that with (among other tools) with a remote "telnet your.mail.server.host.name 587" command or similar; that's a primitive (but effective) (common) port test.
With the Apple Mail client, make sure the SMTP server is configured to use the default SMTP ports. Mail > Preferences > Account > Account Information > Edit SMTP Server > select the target SMTP server > Advanced > select "use the default ports (25, 465, 587)" and consider using SSL and authentication. (Apple Mail tries a few ports automatically, so the set-up can be different than other clients.)
I don't have enough space here for a full write-up on how mail or IP works, and setting up an arbitrary mail client or an IP network can be an adventure; I assumed the Apple mail client in the above. See the user collaboration services disscussion of mail services in the Mac OS X Server Advanced Administration manual as some background. (And if this stuff all looks a little cryptic, that's understandable, and you might want to consider getting some set-up help or consider moving to hosted mail services and making this stuff somebody else's problem.)

Mail Delivery System Notifications won't go away

Hi all
Tiger 10.4.11, MacBook Pro, Apple Mail.
I have several Mail Delivery Status Failure notifications that I cannot get rid of. I delete them, they go in the trash, but I go into any other mail box and when I come back to the inbox, there they are again. Right now I have 5 separate messages, all exactly the same. The problem is that I e-mailed someone something that was too big for their server and got this as a notification. But I can't get rid!
I've junked my envelope index, and re-imported and rebuilt the mailbox. I've deleted off my server (they don't re-appear there) and can't think what else to try.
Any help please?
Thanks

I have now sorted this out - any kind of deleting didn't work, but using the "cut" command from the mail menu bar did.
Thank goodness, it's been driving me mad...

Mail delivery errors

Hi, recently I'm getting tons of Mail Delivery System errors. 69 today alone. When I delete them, they come right back. Many are the same email and sometimes the page is blank. Very weird. The only thing i did differently was to try and set up a rule for people to know I was on vacation. Did not work, and had hundreds of MDS errors upon my return. Have deleted the rule but still not working properly. I also have to force quit on mail often to get it to shut down. Any ideas how to clean this up?
Cheers

I've got the same problem. One thing that helped was to clean out my inbox on my ISP's server. That stopped the force quit problem, at least for now, and also stopped a problem where mail received after that Mail delivery error message wouldn't come into my Mail application. BUT I'm still getting the tons of Mail Delivery System error messages, and yes, even when I delete them, they come right back. The message, which seems blank until I double click on it to open it in a new window, was correct. One address I'd sent an email to is no longer good, which is why one of those messages would have made sense. I see that there is a Windows virus that does this, and am wondering if there might be a Mac one also???

Account error no mail delivery

Greetings
I have a stuck account. i have reconstructed (mailbfr-m) several times, yet mail sits in the queue with a Temporary Failure notice.
many flushes.
I removed the account from Master and re-entered it.
I moved the mailstore to a new location. and did a reconstruct. I can log in and see mailbox, but no delivery for this user.
flush again,... no delivery.,
any insight

i was trying to avoid resetting everyones Read/Write status, but reconstruct on the whole DB fixed my delivery problem. ::solved ::
