PMG and mail client (Outlook, Thunderbird...)


Sep 9, 2018
Hello , sorry for my English,
I use postfix(webmin) and proxmox mail gateway 6.0 , and everything works fine (i can send and reicerve to gmail , yahoo...)in webmail only, but when I use outlook or thnderbird I can receirve but I can't send (The recipient has been deleted or does not have an e-mail address) JUSTE WITH WEBCLIENT .
Please Help MEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
That's odd -you need to send via the downstreamserver (webmin) - also compare the config of thunderbird to what you have configured in your webmail.

This is not an issue with PMG

I hope this helps!
the log from PMG said connect from unknown (IP Public)
NOQUEUE: reject: RCPT from unknown[IP PUBLIC]: 554 5.7.1
you need to send via the downstreamserver (webmin)
configure thunderbird/outlook to send e-mail via SMTP to your webmin server (best with SMTPAUTH).
alternatively you can relay via PMGs internal port (default port 26) - but you need to make sure to only allow a small number of networks there (otherwise you're gonna be used for spamming via your IP address)

I hope this helps
Tanksyou for all ,
My smtp server dont have a SMTPAUTHENTIFICATION ( maybe this is a probleme?!!!)
