Hello Sandy & Per,
first I list my configuration, I work with IPv4:
master.cf:
smtp unix - - n - - smtp
# ^ first IP for all except example.com
# bind second IP for example.com
smtp155 unix - - n - - smtp
-o smtp_bind_address=xx.xx.xx.155
- - -
main.cf:
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay
- - -
/etc/postfix/sender_relay:
@example.com smtp155:
- - -
I did postmap sender_relay and rcpostfix reload.
- - -
dig example.com:

So it works like transport basically?
I send a test mail:
mail -r [EMAIL PROTECTED] -s test [EMAIL PROTECTED]
It returns the described error:
<[EMAIL PROTECTED]>: Host or domain name not found. Name service
error for name=smtp155 type=AAAA: Host found but no data record of
requested type
What's the meaning of "Host found but no data record of requested type"?
Why does it work if I have a empty /etc/postfix/sender_relay? Without
DNS errors?
Thanks.
