OS10.7.5 update blocked outgoing Mail

After installing the OS10.7.5 update from Software Update onto a Mac Pro, I cant send email from Mail. I have 3 accounts with 3 different SMTP outgoing servers and all 3 are listed as 'Offline'. Why has this occurred and how can I switch them 'online'????
I have verified the SMTP settings which are unchanged and all 3 are correct.
Weccome suggestions and any explanations ?
Thanks

Yes, I agree the problem is related to the 10.7.5 upgrade through Software update.
I have a freind with me now, also with a Mac Pro of same vintage, but has not upgraded to 10.7.5 Interesting think is that her mail works fine of my BT hub. She has no problems with SMTP servers and gets mail in and it happily goes out.
Seems it must be within the Mac upgrade, but is there a solution???
Could all those skilled Mac linked members of the forum offer their wisdom and even suggest solutions we can try? Please?
Would downloading and installing a complete Comby 10.7.5 and reinstalling be wise or may it just bring new, additiona problems.???
Welcome any suggestions please

Obsessive emailing- how can i block OUTGOING mail ??

aside from getting therapy, a lobotomy, or this person beaming up to another dimension, how can i stop myself (via MAIL) from emailing them?? i mean, RULES doesn't have a way to block your own outgoing mail.
i know i sound insane and it's a matter of self control but i would love to PROHIBIT my MAIL from sending outgoing to one recipient...

amy --
BDAqua is offering really good advice.
As always.
Another thing you might try is
write the email
print it out
delete the email
put the copy in a box.
Everytime you are temped to respond
do the same thing.
You'll let some steam out -- feelings . . .
And the copy will give you validation.
Just never, never actually send it.
It's worked for me for a long time.
Most times when I'm tempted to really let someone have it,
or I know I'm out of control,
I write the letter, print it out, and press the delete key.
It also helps to put your favorite music on afterward.
Hang in there, Amy.

How can i block outgoing mails to particular domain

I have just set a mac mini with snow leopard server . Configured mail in it . I want to block the outgoing mails to some particular domain or all domains other than my server domain .
please help

Hi Fritz:
Your English is FAR better than my Deutsch (Ich bin ein Wisconsonite). I can barely ask for the train to Zermatt (one of my favorite places on Earth).
Anyway, I think I understand your question. If you mean is there a way to stop the recipient of an E-mail from actually getting it (after you sent it), the answer is no (in Apple's Mail application). Entourage (a Microsoft application) is a good program. As I recall (I used Outlook years ago in my corporate world) the Microsoft mail applications have a feature to "un-send" E-mail). However, I think that only worked if the mail was sent to someone on the same network. You could not retrieve mail from someone outside your own network.

FIXED: Blocking Outgoing Mail

Dear Verizon Community:
Thanks to your enthusiastic participation in Verizon Community and willingness to assist our technical support teams, Verizon successfully identified the root cause and fixed the intermittent outgoing email issue experienced by some of you. (Note: robtoy was especially instrumental in helping Verizon troubleshoot this issue.)
Thank you again for your support and business!

I cannot send e-mail. Answers to date are beyond my capacity to use. How do I contact Verizon to fix?
Why don't you try asking here? There are a number of people who I am sure are willing to help. Since you just registered today and have only one post, it appears you have not asked your questions here. And you need to try to be specific, error messages you are getting, server definitions you are using, what email client, etc.

How are you trying to update? Over the air or connected to computer?
Mails blocked? What is happening when you try to get mail?
Are you seeing any error messages? A little more info would be nice.

Outgoing mail server appears blocked by mobile network

I have already contacted Roadrunner to find out why the host name in the Outgoing Mail Server--mobile-smtp.roadrunner.com will not work. They state that it should read mobile-server.roadrunner.com. When I typed that in, it reverted back to the original phrase, and they said to get in contact with the mobile network. There must be a block in it. We tried a different port, however, that did not work either. Has anyone had this problem? I am receiving emails from roadrunner without incident.

Try deleting the account and selecting manual set up. Also you can also try using an email app from the play store like k9 mail.

Relay Outgoing Mail Through Host Not Updating

We relay our mail through an external company and I have added the entry to Relay Outgoing Mail Through Host field and enabled the tick box. What ever I do I cannot get these changes to take affect. I have tried modifying the main.cf and enabled the relay option without any joy. After modifying these I performed a full restart but it still hasn't taken affect.
This has been working up to now but after a power cut stopped for some reason.
We are running Mac OS X Server 10.4.8.
Thanks
Ross

I'd noticed a small glitch with the GUI during earlier testing. Might not clear things for you but worth trying...
Set it with the Relay Outgoing Mail ticked and relay server entered - click Save.
Wait for whirling update thingy to stop.
Delete the relay server name then tab out of field (field fills with greyed out "relay.example.com"), only then untick the option - Save.
Wait for whirling update thingy to stop.
Tick the option, fill in the relay server - Save.
If no change, people will probably need the unedited output from "postconf -n" and an example mail.log entry showing an outgoing message leaving the server.

Blocking outgoing empty subject mails

Hi,
I can drop empty subject mails easily on the incoming side, but how do I drop or redirect outgoing empty subject mails?

A few things:
1 - I think you just copied and pasted the HTML content, including buttons and pull down menus - some of that output makes it difficult to understand the actual filter settings. i usually ask people to send either a screen shot, or send the output from the "outgoing / incoming content filters screen" with the "rules" view selected. mine looks like:
2 - I don't know if your second condition will ever be met:
'^FW:$'.
Instead, I would use something like '^(i?)FW:$' (and I would even add '^(i?)RE:$' too). Here's what mine looks like:
empty_subject: if (subject == "^(?i)FW:$") OR (subject == "^(?i)RE:$") OR subject == ("^$")) { alt-rcpt-to ("[email protected]"); }
the only reason I can think of this not working are: A) the sender / recipient is placed in the wrong outgoing mail policy or B) there is a content filter matched before hand that is bypassing this one. perhaps you could send in your mail_logs from a test message for debugging?
thanks!

Outgoing mail issue with my domain

All right I'll lay it all out in as much detail as I can...thanks in advance for any insight you can give me.
OS: Tiger 10.4.7 (latest security updates)
Mail ver: 2.1
I have three e-mail accounts: gmail, dot mac and my own domain.
As of right now, I can send outgoing mail through my gmail and dot mac accounts. My domain mail is dead when trying to send through Mac Mail.
Gmail settings:
SMTP: smtp.gmail.com
Port: 587
SSL: On
Auth: Password
Username: (myaddress)@gmail.com
Password: (mypass)
Dot Mac settings:
SMTP: smtp.mac.com
Port: 25
SSL: On
Auth: Password
Username: (my username)
Password: (mypass)
Domain settings:
SMTP: mail.(mydomainname).com
Port: Tried 25, 587, 110
SSL: tried both on and off
Auth: tried none and password
Username: Tried just my username and tried full with @(domainname).com
Password: tried Webmail pass and control panel pass
Again, I have no problems sending with the other two accounts. But I get "could not send message using server mail.(domainname).com" error message. This after the spinning wheel for about 30 seconds.
Now, both the incoming and outgoing server are mail.(domainname).com. I can receive messages through the account just fine. And I can send mail through my Webmail setup at my domain name, too.
I contacted my host (iPowerweb) and they set up a test account and said they are not seeing smtp issues, either.
I recently switched hosts and I was having the same issue with the previous host, too. In fact, I used to be able to send e-mail through my previous host with the same domain, but it just quit working one day.
I do not believe it is a port issue as I am able to send on both 25 and 587.
Previously I just accepted that I wouldn't be able to use Mac Mail to send through my domain. But I am unwilling to accept that fact anymore...
Any ideas folks?
Again, thanks...
PowerBook G4 Mac OS X (10.4.7)

Hello, and welcome to the Discussions.
Typically, Port 587 would require at least Password Authentication -- using None as Authentication would not be expected to succeed. If None is the correct setting, then Port 25 would be the necessary Port.
The fact that accounts in the same domain work, is not definitive, in my opinion, since it might be permitted without Authentication, whereas other sending activities might not.
Without regard to blocking, sending with a third party SMTP involves establishing "trust", and trust is either established by Authentication, or by being identified by the venue where your ISP can ensure you are trustworthy, and this typically must require the use of Port 25.
The change might be that as a Spam fighting measure, your ISP has only just now required authentication on Port 587, although I think this has already been nearly universal.

I upgraded the software on my Time Capsule and outgoing mail stopped on my Mac Air

Hi
I upgraded the software on my Time Capsule and outgoing mail stopped on my Mac Air
My colleagues are using my Time Capsule on their Mac Air (with Lion OS System) and Dell with MS OS System.
I am on OS X 10.6.8 and was sucessfully using SMTP for outgoing mail .... after my update for the Time Capsule, Mail on my Mac Air stopped
Why?
Thanks in advance
Jan

Hi Garmulewicz,
Can you tell us a little bit about the SMTP service? What port is it set to use? Authentication SMTP? Have you tried manually sending over Port 25, 587 or 465? If you bypass the Time Capsule can you confirm that SMTP traffic still works behind the same modem?
I've personally never seen an update break SMTP, that would imply that the update somehow is blocking the port where SMTP is occurring. What if you configure a personal GMail account or something else, does that work?

Outlook 2007 - Outgoing mail server from a 3rd party

I tried to set up the outgoing mail server for my Outlook 2007 with a 3rd party mail server. e.g. mail.xxxx.com, and I could not send the e-mail at all. If I set up the outgoing mail server as outgoing.verizon.net, I can send the email to everyone else but not to this 3rd party mail server mail.xxxx.com. I received the undeliverable message from Verizon that the mail was rejected due to not being able to log on to this 3r party mail server. I am working for this company from home and it requires me to set up this for my outgoing mail server. Does anyone know how to fix this, including specifying what needs to be done at the 3rd party mail server to change to accept emails sent from outgoing.verizon.net? Thank you in advance. Andy

Port 25 is the standard for SMTP, although some now use a submission port, 587. I know port 25 off network is blocked for residential users, I don't know if 587 is blocked off network because I have never tried it. I suspect it is. Verizon is by no means the only ISP to do this.
Business accounts do not have blocked ports as far as I know, so if you have a business account, you are free to communicate using port 25 anywhere.
Verizon has recently gone to non-standard port assignments for SMTP and POP servers. see

Server App: Outgoing Mail Relay not working

Hi,
I'm trying to set up Outgoing Mail Relay on my Mountain Lion Server, but I always get bounced emails:
Oct 1 04:33:34 my.server.private postfix/smtp[9582]: C855DCE700D: to=<[email protected]>, relay=mx2.sub5.homie.mail.dreamhost.com[208.113.200.128]:25, delay=0.91, delays=0/0.02/0.65/0.24, dsn=5.7.1, status=bounced (host mx2.sub5.homie.mail.dreamhost.com[208.113.200.128] said: 554 5.7.1 Service unavailable; Client host [myIP] blocked using zen.dnsbl; http://www.spamhaus.org/query/bl?ip=myIP (in reply to RCPT TO command))
If I use in the SMTP servers list of Mail app, the exact same account credentials, the email is been delivered only when using SSL. So, I tried adding :465 and :587 to the ougoing relay server in the Server app (Relay outgoing mail throught ISP), but I get the following error and the message stays queued:
Oct 1 04:13:41 my.server.private postfix/smtp[8920]: connect to mx2.sub5.homie.mail.dreamhost.com[208.113.200.128]:587: Connection refused
Oct 1 04:13:41 my.server.private postfix/smtp[8920]: connect to mx1.sub5.homie.mail.dreamhost.com[208.113.200.127]:587: Connection refused
Oct 1 04:13:41 my.server.private postfix/smtp[8920]: 0BAD1CE6340: to=<[email protected]>, relay=none, delay=369, delays=369/0.02/0.43/0, dsn=4.4.1, status=deferred (connect to mx1.sub5.homie.mail.dreamhost.com[208.113.200.127]:587: Connection refused)
It seems I'm missing something. I want to use smtp account to send all the email coming from my Mac OS X Server, but it looks like I'm doing something wrong or the Server App doesnt work the same way Mail App does when connecting to a SMTP server.
Any comments?

Let me add....
Mail app is connecting and sending the emails correctly with the same credentials but using SSL through port 25:
READ Oct 01 05:04:01.566 [kCFStreamSocketSecurityLevelTLSv1SSLv3] -- host:my.externalrelayserver.net -- port:25 -- socket:0x7f890be0c620 -- thread:0x7f890ca3dd70

235 2.7.0 Authentication successful
I would like to force Server App to do a SSL connection to port 25 of the specified relay server, but not sure how to do this. If I don't manage to do SSL on port 25, then, my relay server will bounce the emails...
grrrr!

Outgoing mail is not working on the Macbook Pro

Hey
I am using the mail client to read my gmail mails in my Macbook Pro. Incoming and outgoing emails were working fine and all of a sudden for the last 2 days my outgoing mails are not working and i get this error" the sender address blah blah.com was rejected by the server".
I reentered my cred in the pref pane and it still does not work. I am able to send mails fine using the browser. Incoming mails is fine is fine on the client.
Any idea what is causing this error?
Thanks

Mac Mini, MacBook Pro Mac OS X (10.4.5)

I'm not sure why this worked fine for a period of time but most, if not all ISPs use for connecting to the internet block the use of SMTP servers outside of their network (or not provided by the ISP) on Port 25. Some ISPs allow the use of an authenticated SMTP server only that is outside of their network on Port 25 but some block its use regardless.
These restrictions are in place as part of an overall effort to prevent spam emanating from the ISP's domain.
Something to try.
Go to Mail > Preferences > Accounts and under the Account Information tab for the account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
If this doesn't work, you need to add your ISP's SMTP server to mail and select this SMTP server to send mail with your gmail account which is invisible to all recipients.

Outgoing mail server will work on Iphone but not Mail on Macbook

My POP account will send mail on my iphone no problem, but on the mail program on my macbook it times out. All the account information is identical. The mail program keeps telling the server does not support port 995, but on the Iphone it does. I have tried changing the port but it still won't work. Suggestions please!

misilulu, outgoing mail uses the SMTP protocol on ports, 25, 587 (for submission only) and, in the case of SMTPS, port 465 (rarely used and deprecated).
The POP is used for incoming mail on ports 110 or, in the case of POP over SSL, 993.
If all the settings between your iPhone and your MacBook are the same and you are having problems sending outgoing email on your MacBook it is most likely because you are using the wrong port. If you are using port 25 then it is most likely that your ISP is blocking that port for all mail servers except their own. If that is the case try the mail submission port 587. If that doesn't work then try 465 as a last resort.
