Hi all! I am trying to setup my carbonio 25.6.1 so that I can use separate IPs for each of my 2 domains. The main reason for this is spam rejection by server providers. If I have mail.domain1.com as my primary domain and IP 1.1.1.1 pointing to it, and mail.domain2.com with 2.2.2.2 pointing to it, I need a way to have SMTP HELO banner say mail.domain1.com and mail.domain2.com respectively.
I was able to modify ` removed link `
smtp-navara unix - - n - - smtp -o syslog_name=postfix-smtp-domain2 -o smtp_bind_address=2.2.2.2 -o smtp_helo_name=mail.domain2.com
And I can confirm that for outbound emails the server is authenticating as mail.domain2.com.
However if I test
swaks --server mail.domain2.com --port 587 --tls -q HELO
I get
=== Trying mail.domain2.com:587... === Connected to mail.domain2.com. <- 220 mail.domain1.com ESMTP Postfix -> EHLO superuser-X570S <- 250-mail.domain1.com
I would really like to use a single carbonio server and allow the 2 domains to use separate IPs.
not sure how to configure this, since now I see that carbonio listens on 0.0.0.0:587. Any ideas? Thanks!
