Hi All
I am planning to migrate from qmail to postfix.
Currently our qmail uses QMAILQUEUE, qmail-scanner, clamd,
spamassassin, rbldnsd, greylite, qmail-pop, qmail-ldap, virtuals and
ezmlm.
(I hope I did not miss anything)
I found few suggestions from the following articles
http://www.irbs.net/internet/postfix/0207/1241.html [yr 2002]
http://www.irbs.net/internet/postfix/0401/1049.html [yr 2004]

They are pretty old.
It seems you managed to miss the postfix documentation.
http://www.postfix.org/documentation.html
It's so odd that people insist on NOT using the actual documentation.
Is there any new feature(s) relevant to qmail to postfix migration,
that are not covered above and, were
introduced in newer postifx?
I would not recommend following old, or unsupported, documentation.
Always use the latest official documentation, it includes the versions
something was introduced at.
Also, if you followed any of those threads, is there some gotcha that
might be missing in there?
They're probably flagrantly wrong in about a dozen places. They always are.
I am guessing I need to install postfix as the front-end, will be
installed on a separate new box.
Then use the qmail, currently running on the existing system, as the back-end.
Hoping that will ease the migration, however not exactly sure how to
do it, quite yet :-).
I would suggest the opposite. postfix is much more flexible than that
old crone.
However, you can do it in any way that suits you.
(I have to go back read those threads/articles again.)
Then eventually expire qmail. Not quite sure how to do that either,
but I think have to do some
MX tricks on that.
Anyways, I am looking for comments/suggestions.
Thanks
Start with the URL Wietse gave you, it covers the basics.
