SMTP Auth works on and off

[Meni]

i am using a system that was installed using the awesome virtual users with postfix and mysql tutorial (THANKS!).

Everything works fine., except for a weird SMTP issue.

Testing the system - I am sending mail to another account I have.
Mail goes through, but only sometimes.
In other times - i get relay denied errors...

I am using authentication as instructed, AND I also ticked the encrypted authentication checkbox in my local outlook client.

output of telnet to port 25 on the server is:

250-mail.domain.com (this is obviously changed...)
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250 8BITMIME

and mail.log has these lines in it (among others)

Jun 11 20:52:12 mail postfix/smtpd[6410]: NOQUEUE: reject: RCPT from blablablablabla[xxx.xxx.xxx.xx]: 554 <meni.milstein@gmail.com>: Relay access denied; from=<meni@domain.com> to=<meni.milstein@gmail.com> proto=ESMTP helo=<comp1>


Any ideas?

Plese post your postfix main.cf configuation file.

I am sorry.
It turned out to be an outlook (or should i say LOOKOUT) issue.
If you manually edit email account settings from WITHIN outlook the edits will not ALWAYS kick in...

You should always shutdown outlook and go to the control panel -> mail, and edit the settings from there.


Thanks...
