Install mail servers

Step 7: Install Web/POP3/IMAP servers

Install either of the following IMAP & POP3 servers (see note):

toaster_setup.pl -s courier
toaster_setup.pl -s dovecot

and then a webmail client or three:

toaster_setup.pl -s squirrelmail
toaster_setup.pl -s sqwebmail
toaster_setup.pl -s roundcube

Courier -vs- Dovecot -vs- Binc

Courier has been the default IMAP server for many years. However, vpopmail support has always been a second class citizen to most of the courier developers. It has also been a persistent nuisance to keep working reliably due to frequent changes. However, it works well, scales well, and is still a supported feature of Mail Toaster.

BincIMAP = Binc is not Courier = a replacement for Courier. I evaluated it a long time ago and wasn't impressed. I don't remember why, but IIRC, my biggest complaints were performance related.

Then came Dovecot. I've watched the project for well over a year and have had Dovecot running on a personal mail server. Other than being a pain to get set up (because there wasn't any docs yet!) so long ago, it has been an extremely dependable POP3/IMAP server. It also builds much, much faster than Courier. Configuration is not yet intuitive but is no longer frightening. I highly recommend Dovecot.

Configure Courier-IMAP (optional)

Courier includes some generic settings in its SSL config files (*d.conf). If you edit those files, you can have your own values reflected in your SSL certificates that are used for the IMAP-SSL and POP3-SSL servers.

cd /usr/local/etc/courier-imap
vi pop3d.cnf imapd.cnf quotawarnmsg
cd /usr/local/share/courier-imap
./mkimapdcert; ./mkpop3dcert

Courier FreeBSD note

Newer version of courier-imap and sqwebmail require courier-authlib to be installed. toaster_setup.pl will do that for you. When it does, you will be prompted to select an authentication type. The only one you want to have selected is for vpopmail, AUTH_VCHKPW. In general, if one of these pops up and you don't know what to select, try with only the defaults and AUTH_VCHKPW.

If you don't see this popup, that means the ports maintainer (finally) gave me a way to pass along the right settings and suppress the dialog box. :-)
