When active recipient verification, PMG sends a double-bounce email to the recipient.

I'm getting the errors:

Jan 29 14:22:59 server postfix / smtpd [29452]: NOQUEUE: reject: RCPT from server.domain.com [xxx.xxx.xxx.xxx]: 553 5.7.1 <double-bounce@domain.com>: Sender address rejected: not logged in; from = <double-bounce@domain.com> to = <userdestiny@destiny.com> proto = ESMTP helo = <server.domain.com>

My email server requires me to be logged in and authenticated beforehand.

How can I make the "double-bounce" email authenticated before sending?
 
hmm - either make an exception on your e-mail server to accept mails from your PMG without authentication..
or use the templateing system to change PMG's postfix configuration to authenticate to your e-mail server ...
see https://www.linode.com/docs/email/postfix/postfix-smtp-debian7/
for some information of postfix authentication for outbound mails and
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_template_engine
for documentation on how to use the templateing system

hope that helps!

I added the mynetwork list to temporarily resolve it.

But I will check the possibility of forced authentication.

Thanks!
