Dovecot keeping a cache/index on the server side allows Dovecot to quickly provide information when the clients want to sync up. When a mail client is first started, it needs to do the equivalent of send me a list of all the emails in this folder. If Dovecot needs to scan each and every message, it can be pretty slow, but if it has an index maintained that it can more or less just ship as is, that's much faster. How often these types of overall sync operations occur under normal usage, I don't know. While I'm not an expert, I believe that Courier maintains indexes as well. Fair enough, thanks for your thoughts. I guess I'll give dovecot a spin when the right time comes (apparently it's still in beta). Meanwhile I'll stick with courier-imap.

Re: Mail system Suggestions
On a side note, I found Outlook 2003 really shoddy/poor at working with IMAP based systems, esp when you have lots of rules to run and lots of emails to download first thing in the morning. eg would easily 10 minutes to synchonise, whereas thunderbird takes about 10 seconds!

Martin Hudec wrote: You can give dovecot a try now :), I use it on all mailservers in production environments. It handles my ~54k mails in my mail account pretty well (only slowdown is detected if I use gprs connection ~56kbits). One good thing that counts in for dovecot is that postfix in its current 2.3.x line is able to do smtp authentication directly via dovecot (so no use for sasl* packages) to any backend you use (mysql, ldap etc.) in your dovecot config. Nice and clean. More info: http://www.postfix.org/SASL_README.html#server_dovecot Dovecot with its 1.0 version is pretty stable now, I have been using it since 0.99.x versions (now alpha port is in use, upgrade to beta is planned). Courier-imap is good choice too, I have no objections to it, but my one subjective one perhaps: in its older versions (3.0.x) it seemed to have some kind of psychic problems when dealing with Thunderbird mailclients. Then I switched to Dovecot. Thanks for the info.

Mail system Suggestions
I am setting up a simple mail system that will accumulate 20 people. I already have Postfix installed. I was wondering what users would suggest to complete the system. I was thinking of Cyrus-Imap or perhaps Dovecot or maybe something else. I definitely want an imap system. -- Gerard Seibert [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

A recent discussion on the list showed a lot of support for Dovecot - it should be easy to setup for a single domain. I use Cyrus, but I might try out Dovecot if it supported virtual domains. If you ever need to migrate between various imap servers because you redecide, then you can create a perl script to move the mail using the imap protocol, then you don't need to care what server is running.

For a small system, Courier-IMAP is easy to set up and the users' mail is stored in their home directories under Maildir. --On July 22, 2006 5:50:10 AM -0400 Gerard Seibert [EMAIL PROTECTED] wrote: I am setting up a simple mail system that will accumulate 20 people.
