Plesk 11.5 smtp_auth: FAILED

[sebas]

Hi,

Today we have the problem that smtp_auth is not working.

The same users that yesterday were able to send mail, are not able to send today. They can receive, but the cannot send.

The message in the log file is similar to this:

Jul 3 09:55:50 canada7 smtp_auth: SMTP connect from dsl-xxxxx.com.mx [xxxxx.73]
Jul 3 09:55:50 canada7 smtp_auth: FAILED: [email protected] - password incorrect from dsl-xxxxx.com.mx [xxxxx.73]

It is like if send password and receive password were out of sync.

It is possible to send mail through webmail.

Qmail has already been restarted from services in the tools and setting but is still failing.

Thanks for your help,

Try to switch your server MTA

In the end, webmails use same mechanisms to send email. Therefore problem is in the way users send mail. What do they do exactly?

Also, there is no such thing as send password and receive password. They are one and the same.

/usr/local/psa/admin/sbin/mchk --with-spam

/usr/local/psa/admin/sbin/mchk --with-spam

This was the solution.

Thanks for your help.

Great. I had the same problem than you after the 11.5.30 update. i solved it with this tool too.

I was having problems with smtp authentication on port 587, asking everyone for password, and this mchk command solved it. Thanks.
