Yes, for a small up to middle size mail server (POP3/IMAP) dovecot should be the choice. Especially if you was satisfied so far with the uw-imapd. > The dovecot wiki has good support documentation for the migration but > before I jump in I'd like to get some opinions from people on this list > on what to watch out for, etc. that will make the migration as smooth as > possible. Work with backups made first! In this case you don't risk any data loss either which faults might happen. Here on the list I did only read 1 or 2 postings where people reported problems with the Outlook mail client: for some mail users all was fine after migration, for others not. IIRC it is a known Outlook bug. > As near as I can tell, it looks like all I need to do is save the > current sendmail configuration, the current /var/spool/mail/* files, > install FC3 fresh, restore the sendmail config and /var/spool/mail/* > files, enable and configure dovecot per the wiki migration notes and > then reconnect the system to the net. And it will work like a charm. :-) The changes from Sendmail 8.12 (RH9) to Sendmail 8.13 (FC3) aren't that big. So you should be able to keep the sendmail.mc as it is. Just be sure that a "make -C /etc/mail" will not spit out any errors on the FC3 system. Keep care to preserve the UIDs/GIDs of your system user accounts. Else you will have to change ownerships by hand on the spool mboxes. Yes, following all advices from the dovecot Wiki will bring you safe from point A to point B. > I use TDMA for spam control now but would love to hear opinions on why I > should either keep TDMA or switch to spamassasin from those who have > faced that decision. You run a web shop and use a Challenge/Response system for mailing? This is practical? I have very good experience by running Sendmail along with ClamAV-milter (anti-virus protection) and SpamAssassin (spam classification, bound to Sendmail using MimeDefang). milter-spamc is too a very good tool to integrate SA into SM mail stream. > -pmr Alexander -- Alexander Dalloz | Enger, Germany | new address - new key: 0xB366A773 legal statement: http://www.uni-x.org/legal.html Fedora GNU/Linux Core 2 (Tettnang) on Athlon kernel 2.6.9-1.6_FC2smp Serendipity 18:48:23 up 9 days, 13:35, load average: 0.05, 0.23, 0.26
