Outgoing mail suddenly rejected by ISP

since 5/6 days my outgoing mail is rejected by ISP and stays in the outbox after all worked fine for several month.
Browsing the internet like being here..... receiving mail from a different account all works fine, through the same wireless ISP connection, which suddenly rejects my outgoing mail.
here are some screenshots
confusing is that Airport Utilities can't find any wireless devise , even so I am using it, see screenshot
can somebody help????

I could sort my e-mail out today, the problem, was with the ISP new setting arrangement
about, there are two questions left :
b) Also why I was using the TPG wireless internet connection on the 02.05.2011 @ ca.1150pm, my macbook pro brought up a message like"somebody is using your (my computers) IP address, the settings changed". Can you make any sense of this or explain, what has happened???
c)Also, when I bring up my 'Airport Utility', while I am connected to TPG and even actively browsing the net on wireless it say's " it can't detect wireless devices (see screen shot above)

HT1277 My outgoing mail is rejected by the server but I can receive e-mails. This problem just started 2 days ago. What changed?

I am unable to send e-mails from one of my acounts. I receive an arror message that the e-mail address I am sending mail from is rejected by the server. I have my outgoing mail set to smtp.comcast.net. I am able to receive e-mails on this account.

Hello,
Is the outgoing server set to...
smtp.comcast.net
Port 465
SSL on

Outgoing mail server rejected password - using microsoft exchange email

hi everybody,
so i have a microsoft exchange outlook email account from my school. i recently have started having troubles with apple mail sending messages. it rejects the password of my email account. i have gone to outlook.com several times and changed the passwords but to no avail. i know it used to work. i went on a trip to guatemala and came back and now it seems to hate me. i cant remember if the problem arose after my switch to snow leopard either..
i went to the help section on the outlook page after i log in but after i change to those settings its still rejects my outgoing mail password.
is there a bug with snow leopard? oh good as i am writing this mail just 'quit unexpectedly'..aww the joys of just having microsoft email- imagine a whole operating system based on such inadequacies (i must vent.. this is extremely annoying that i have to reply back to people with my gmail account)..
thanks in advance!

It is likely the Port setting for the SMTP has either gotten changed while you were away, or your provider has changed what settings are needed. Check the settings carefully. If you know exactly what Port should be used, change to Use Custom Port, enter the Port manually, and proceed to test again.

Outgoing mail server rejects mail

Hello,
My ISP's SMTP server started rejecting the outgoing mail I am trying to send through it. I called them, but they checked the settings with me (which as far as I know had not changed). They said they were OK and that I should call Apple.
Does anyone know what would cause this I restarted the computer and the modem/network completely. It still does it. I have a pc on the same network which is able to send mail through the same SMPT server, so it does seem like something on this mac maybe. Any suggestions?
Thanks
Bob

How do I stop my outgoing mail being saved (in trash) every minute

Since downloading Yosemite each outgoing mail is saved every few seconds, meaning that there are, sometimes around 15 separate "savings" of one email, each with a few more words more than the previous one. These are saved in my trash box. How do you stop this from happening? I should point out that it is only mail from the Google mail box that does this, not the iCloud.

ICloud SMTP as Freemail.hu's outgoing mail server "rejects sender address"

Using verified settings of iCloud's as outgoing server (smtp.me.com, working iCloud username and password, SSL on or off, password authentication, server port 587) as of my freemail.hu (hungarian mail service provider) account on my iPhone 4 iOS5, letters sent from my freemail account arrive in Outbox as Unsent Message with the error message "The sender address [email protected] was rejected by the server" - with checked working apple server at sending and otherwise perfect iCloud mail account. Any suggestions? Thanks in advance...

I realise you don't intend to send spam, but unfortunately there are plenty of spammers in this world who would happily use Apple's servers to send out spam. That's why Apple lock it down to @me.com and @mac.com addresses only.
GMail will allow you to send external email through their servers once you have performed some identity verification through your external email account. That may be an option for you.

SMTP Outgoing Port being rejected by my Z10.

Just got my Z10 last week and everything with the phone is awesome thus far with the exception that i cannot send any emails out. I am able to receive but for some strange reason in keeps rejecting my outgoing port of 587. Spoke to my tech people who host the email and they said the issue has to be coming from Blackberry as the have been receiving other inquires from other clients who use there service and have also recently purchase the z10. I have seen on some other forums that this is a known issue but have not been able to find a solution to the matter. Please help

Welcome to this place! I presume you are running 10.1 OS? The "easy" way out of this dilemma seems to be to send your mail w/o security (and thus on a different port) but you may not be able nor want to do that. For instance, my account requires me to send w/o security as it is an asmtp (not smtp) so it doesn't need it. Someone else here may have a more up-to-date answer as the 10.1 OS seems to have solved this for many.

New Godaddy sent mail being "rejected by server"?

I just received my iPad 2 last week & tried to setup my Godaddy email account on there like I have on my iphone 4.
I copied all the mail info off my iphone 4 exactly when I was setting up the new "Other" mail account on the iPad.
I am able to successfully receive emails, but when I try to reply or send them I get the following error:
Cannot Send Mail - A copy has been placed in your Outbox. The receipent "[email protected]" was rejected by the server.
So what is wrong if the iphone can send mail out of that account when all I did was copy the info to the iPad?
Thanks.

Psychedelic Wonders,
Came across your post. Hope you have been able to get it configured. In case you haven't seen these, here are the instructions we provide for iPad: http://x.co/XpNl. Make sure that you have tried other ports too. Here are some troubleshooting tips: http://x.co/XpNt. Hope this helps!

How can I get outgoing mail in Mail program to work consistently?

Some times using Mail messages can be sent immediately on any of my several accounts including a gmail account. Other times no mail can be sent perhaps until the next day. It just read sending. If I transfer my outgoing gmail messages to gmail on safari I can send it immediately. I am changing no settings and incoming mail is coming in without difficulty. This is most frustrating if I am trying to response to a message and I can't get it out until the next day. Any suggestions? Thank you

I have had sbcglobal dsl and now Uverse and periodically have had the problem of outgoing mail being rejected by the smtp server. The problem has been changes made at the server by the isp. I make no changes and things go from working to not working. Over the last 6 years I have gotten pretty good and "fixing" the problem by deleting accounts and reentering the data in the Mail program and at the AT&T website. A process they call verification is involved. Now it is broken and it is unfixable.
I have spent the better part of the last 3 days trying to get a third party or vanity email address to verify. The panels say I have successfully verified my address but it will not send. Along the way I have read a lot of stuff on various forums and am thinking that the issue may be the same between at&t and other big providers... they shut down 3rd party address on smtp in their war on spam.
So we called att support and were told we would have to pay for premium support. We asked instead to cancel our service. We signed up with a local dsl service (Houston) and discovered to our dismay that DSL does not equal DSL. The local service has never been able to swap over a Uverse dsl service. So we were back to Uverse to have Uverse dsl canceled and regular at&t dsl installed.... it is like dealing with two different companies. Along the way we discover that at our location we will lose the 6 Mbps service and only be able to get 1.5 Mbps... our modem will have to be changed out and at this point we are sad and weakened. The Uverse rep offers to lower the premium support charge from $30 to $15 so we gave in and signed up for it. The next day I get the very polite and seemingly competent Paulo on the line. We get set up for him to take over the cursor and we start reviewing my settings. Bottomline. I had all my settings perfect... practice, practice etc. They were absolutely correct on every panel. Paulo got to see that the verification does not work and that it is not possible to set up a "reply to" third party address that will work. Paulo was very nice and very baffled. He invited me to call back but he really had no idea about what to do to get things working.
By this time I am feeling pretty defeated and trapped... I cannot reasonably move to another provider and no one at AT&T can make it work. There is a happy ending for me in this though and this could work for someone else which is why I am making this long post. My vanity email is from an email forwarding service where I have had an account for 12 years. My isps change as my job has moved me overseas and back and across the US several times... my email address does not change. The company I use is pobox.com I was looking around at their website and noticed that my service includes use of their smtp server. I printed off the instructions, which they have for about 20 mail clients, pc, mac, et al and within 10 minutes I was sending mail from [email protected]. I got no error messages and when the mail arrived it showed from [email protected] and when we replied to that email it put [email protected] in the to:. Man am I happy! This fix did not cost me incremental $ and it was easy. The service costs $20 per year for a single year subscription... I have a 5 yr which runs me $15 per year. There are other benefits to the service... decent spam filtering and url forwarding.
If you are having a problem with a vanity address not working through your isp smtp server and you can stomach $20 per year, go on over to pobox.com and tell them Pam sent you.
ps the other thing that I got to work was sending mail out from my mobileme account using their smtp server. Mobileme will not allow me to use my vanity address but I am happier having .mac in my return address than att or sbcglobal.

I changed my e-mail address a few months ago everything was ok. Starting monday my outgoing mail can not be sent, it says the server rejected my e-mail address. Why ? I can receive mail but not send it

My outgoing mail gets rejected. I can get mail but not send it.It was working for about 6 months.

If the smtp is rejecting your password you should go in.
Mail -> Preferences -> Accounts
Select your Yahoo account in the sidebar on the left.
In account information tab you will see : " Outgoing Mail Server (SMTP) "
Click on it and choose edit SMTP server list.
Select Yahoo and click on the advanced tab.
Now fill your new Yahoo password.
Hope it's help.

For No. 2, I m seeing that the DNS name is not resolving. How can I be sure this issue is not from my side ?
For No. 3, It seems to be some problem from that domain itself, and even mails from outlook.com are being rejected.
Is there any best practice that I am missing out on ?
How can these issues be resolved ?

Mail: outgoing and now incoming mail server rejects password

Hello all. Hope you can help with this one.
I was using Mail as normal yesterday. I use the same incoming mail server and SMTP server (my university's Exchange server). Then sending mail suddenly failed. The error message I get is:
The SMTP server “exch.wlv.ac.uk” rejected the password for user “(null)”
Enter your password again or cancel.
The settings are port 995 for outgoing mail, using SSL and requiring password authentication.
I've verified my settings and passwords with IT support. They say they haven't altered anything, and nor have I.
I've tried Connection Doctor: it says Mail connected with the exch. server without any problems. However, under Account Information, the server says (offline).
I've changed ports (to 25 and 587): no success.
I've deleted my password from Keychain and Mail plist and reentered it. No success.
I've verified and repaired permissions.
I'm now not getting incoming mail either: the error message is
There may be a problem with the mail server or network. Verify the settings for account “Staff POP” or try again.
The server returned the error: The connection to host exch.wlv.ac.uk on port 25 failed.
I can send and receive using web-based OWA.
Is there anything else I can do, or is it a server problem?
Thanks,
Aidan

May be no help to you Aidan except comfort in numbers. Mail has started behaving erratically for me in the past week. My inbox and account mail has disappeared and my accounts keep being rejected by the webmail host similar to your problem; password rejected etc. Then Mail closes abruptly telling me there's a problem and offering to send a report to Apple. Mail is version 4.5 and the iMac is 10.6.8. Help!
