Issue Incorrect recipient mailname

[tech01]

I'm pretty stuck, researching old old articles which I thought were relevant but not finding a solution.

While all services are running correctly I assume these might be e-mail messages for some kind of alert but all the messaging systems watchdog, fail2ban, etc etc that I can find are setup correctly and I am receiving e-mail the only reference to this issue is Plesk sendmail. Mail does goes through to [email protected] but whatever the maillog info is below is not being sent/received.

Usually, error message "Unable to get sender domain by sender mailname" occurs when email sender address is empty or in short form (without domain part or '@' sign). Since this is not supported under Qmail, such requests cannot be processed and the mail gets bounced back. So, I think that problem in you [email protected] mailname.

IgorG, I have searched just about everywhere that alerts are sent and cannot find why it is referring to one of my 'localusernames' instead of an actual e-mail address. The errors above appear just about every minute or so. Is there any way to track down what is attempting to send message or login etc? This is on postfix.

Some time ago I remembered switching from postfix to qmail resolves e-mail issues, but that isn't the case anymore. Also when switching MTAs I noticed that the interface for postfix changes back to accepting all (both ipv4 and ipv6) and I really need it not to do this on updates or when switching MTAs. It also chunks my send mail IP address by commenting it out of the script, please see if we can not have these changes reverted back.

I get the same results as this user from back in 2014, his post unfortunately went unanswered: https://talk.plesk.com/posts/758501/

Also as far as alerts are concerned all of them seem to be coming through ok. The username that is in the LOCALUSERNAME slot refers to a local account but happens to be the local domain account.

Here is the qmail output...

Hi tech01,

you could try to use:

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

or

plesk repair mail​

in order to fix some misconfigurations.

In addition, it might be a good idea to create a "real", existent root - eMail - adress ( as for example "no-reply" ) and configure your php.ini's with the "real", existent eMail - adress, as for example:

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "/usr/sbin/sendmail -t -i -f [email protected]"

 

[tech01]

I've tried both but what I'm trying to do is find out WHAT is sending these messages that are not being delivered. I tried your other fix with the sendmail path but the errors still appear and I can't track down for example why it has 'pleskuser' or 'LOCALACCOUNT' it is sending from. When I switch to Qmail it would be [email protected]

Hi tech01,

I've tried both but what I'm trying to do is find out WHAT is sending these messages that are not being delivered.

I assume, that these are cron - messages informing you about the successfull execution of the cron task(s). Pls. check your file "/etc/crontab" or inspect your syslog messages directly before the mails are triggered.

 

[tech01]

Didn't think they were cron messages, they seemed to be random in generation possibly relating to some kind of system event notification. But upon further review seems every :01 or :02 past the minute to the button, unless it is actually processing mail at that time and it might delay. Digging deeper.
