I have three mail servers and I need mail for certain users to forward to another box.
On BOX A /etc/aliases are set up => alias: email@example.com
BOX B is FEDORA 5, postfix, dovecot and it will not accept the forwards (or any mail) sent from BOX A.
BOX C is an MS Exchange and BOX B accepts mail from it just fine.
Here is an example error from the maillog on BOXA:
Apr 2 18:11:17 BOXA sendmail: k31LmVgo024751: to=user@BOXB.domain.com, delay=1+01:22:45, xdelay=00:00:00, mailer=esmtp, pri=9300919, relay=BOXB.domain.com., dsn=4.0.0, stat=Deferred: Connection refused by BOXB.domain.com.
I have read the other posts that seemed related to this and still cannot resolve this problem.
so what am I missing?
-thanks in advance
