I have a VPS with multiple IP addresses:
- venet0:0 x.x.x.2
- venet0:1 x.x.x.3
- venet0:2 x.x.x.4
- venet0:3 x.x.x.5
All IPs have A records
- m2.domain.com -> x.x.x.2
- m3.domain.com -> x.x.x.3
- m4.domain.com -> x.x.x.4
- m5.domain.com -> x.x.x.5
and rDNS records
- x.x.x.2 -> m2.domain.com
- x.x.x.3 -> m3.domain.com
- x.x.x.4 -> m4.domain.com
- x.x.x.5 -> m5.domain.com
I have installed postfix + dovecot + mysql + opendkim.
Here is part of my master.cf which starts SMTP:
x.x.x.2:smtp inet n - - - - smtpd -o myhostname=m2.domain.com
x.x.x.3:smtp inet n - - - - smtpd -o myhostname=m3.domain.com
x.x.x.4:smtp inet n - - - - smtpd -o myhostname=m4.domain.com
x.x.x.5:smtp inet n - - - - smtpd -o myhostname=m5.domain.com
When I telnet to m2.domain.com:25 I get the expected HELO m2.domain.com and so on for all subdomains.
All fine, but in the message header I have the wrong
HELO
X-Spam-Last-External-HELO: localhost.localdomain.
I didn't set $mydomain in main.cf and values from master.cf did not override it.
How do I set HELO dynamically for all IPs?
Here is a full header

Edit:
I've seen the related links but the problem is that all outgoing emails will be from one domain (domain.com), so transport maps and multiple instances will not do the job, or I don't see how.
