Rather noddy IMAP & mail & misc questions

[David Given <dg@cowlark.com>]

I have a cable modem and a fairly lax TOS, so decided to set up a
permanent server on it. Which OS? OpenBSD, naturally.

Overall it's been great. The server's running on cowlark.dyndns.org and
I'm sending this message through it. I'm much more au fait with Linux,
and while Linux seems to be faster (don't know whether it is or not, it
just seems that way), OpenBSD seems to be much more polished. Very nice.

So I'm setting it up as a mail server, so I can read my personaly mail
on it from at work. IMAP + SMTP on a non-standard port, basically. I
spent ages setting up SSL tunnels before realising that encrypting IMAP
is futile given that the email will have arrived on the box in plain
text anyway. (I am remembering to authenticate with CRAM-MD5.)

(BTW, ports rules.)

But I get it all working. Sort of. The standard IMAP server, uw-imap, is
awfully big and doesn't work spectacularly well --- you can't put
messages in a folder with children, for example. courier-imap only
understands maildirs. Which is fine, except nothing *else* understands
maildirs. cyrus-imap isn't in ports and seems to require you to
reconfigure your entire mail setup.

Is there a decent, small, efficient IMAP server that works well under
BSD? And on a related note, are there any *fast* IMAP-based webmail
systems I could install? My machine's only a P120 with 32MB, and perl or
PHP4 based solutions are just too slow...

Also, given that this is going to be on the net full time, and it's
already getting hammered with Nimda/Code Red attacks, I'm going to have
to keep it as hardened as possible. What's the procedure for getting
security updates for OpenBSD? There must be an automated way of updating
your ports tree and recompiled changed programs, for example. I've
looked at cvsup but it seems grotesquely complicated. What should I be
looking at?

(BTW, pf rules. Setting up a firewall was a breeze compared to iptables
on Linux. Like, ten minutes work instead of two weeks and still not
getting it right. Nice one.)
