I setup postfix so that root email is routed to my user account.
All mail sent from bittwister uses my ISP email account.
More and more postmasters are rejecting email if they can not verify
the Return-Path contains a valid email account in a registered domain.
diff legend:
lines with < is the before change. line
lines with > is the after change. line
lines with numbers contain the line and character location of changes.
I modified aliases to send root's email to bittwister:
diff aliases_orig aliases
80c80,81
< root: postfix
---
> root: bittwister
I generated the aliases.db with postalias aliases
I created sender_canonical with
bittwister
(E-Mail Removed)
I generated sender_canonical.db with postmap sender_canonical
I modified main.cf with my isp/local host.domain
and added the sender_canonical_map line.
diff main.cf_orig main.cf

After I change anything I do a
postfix stop
cp /dev/null /var/log/mail/errors
cp /dev/null /var/log/mail/info
cp /dev/null /var/log/mail/warnings
cp /etc/resolv.conf /var/spool/postfix/etc/resolv.conf
postfix start
and check the /var/log/mail/* logs
The cp /var/spool/postfix/etc/resolv.conf is because I am on dhcp
from my isp and the spool copy needs to match the /etc copy.
You might find some help in the debug file found with
locate -i postfix | grep -i doc | grep -i debug
You then cut/paste something like
/usr/share/doc/postfix-2.0.6/README_FILES/DEBUG_README
into your browser if running Mandrake.
