Hello.
I see strange mailings in the exim log.

What are these mail send and how can I turn them off?

It's been a while since I last dealt with exim and it's logs (and the question is probably better suited for an exim forum) - but the lines look to me like logs from queued mails, which have not reached their retry time yet - meaning when the mail was first submitted - the next SMTP server responded with a 4xx temporary failure (then the mail gets queued and is delivery will be tried later on)

check your mailq (`mailq` or `exim -bp` should work for that) - if this is indeed the case

else - check your logs for why the mail was not accepted initially

I hope this helps!

What is it /usr/bin/pvemailforward ?

What is it /usr/bin/pvemailforward ?

this is default in proxmox - it's a small binary which looks up the mail-address configured for the 'root@pam' user in the GUI and sends the mail to them (by invoking `sendmail`)

How can I check this sending of mail?
What I specified in the proxmox user parameters.

it should log to syslog and will then call
`sendmail -bm -N never -f <mailfrom-address from datacenter.cfg> <email-address from the root@pam user from user.cfg>` to send the mail - see:
https://git.proxmox.com/?p=pve-mana...7b86bac21b1f516b3969b4f295ad36ca8;hb=HEAD#l36

I hope this explains it

Not understood.
What should be done?

 

[Stoiko Ivanov]

Nothing should be done - the script logs to journal if it sends a mail (or if no e-mail address is configured for 'root@pam')
then it calls sendmail - and exim will forward the mail

the exim log should tell you if there is a problem with mail sending
