Hi Stan
I only have the one account on this server, everything else is relayed elsewhere.
If this is an SMTP relay server, I'm surprised you bothered to install an IMAP server at all. It would have been easier to simply alias postmaster@ to another account on another machine where you do store mailboxes. I.e. simply 'forward' all postmaster mail to you main account and use Sieve to sort all postmaster mail into a folder. This is exactly what I do. It's what a lot of people do, especially those handling many domains, and thus having lots of postmaster addresses.
A question about where the mail is actually supposed to be delivered to... initially I configured Exim4 to delivery the email to ~/Maildir and I noticed as you saw in the list directories like ~/Maildir/new and ~/Maildir/cur, however once I configured Evolution to login to Dovecot I noticed the directories ~/Maildir/INBOX/new and ~Maildir/INBOX/cur were created. Should therefore Exim4 be configured to ~/Maildir/INBOX instead of just ~/Maildir ?
Configuration of maildir can be a little confusing the first time around. Given your situation/server, I'm really surprised you didn't use mbox instead. It fits this scenario much better than maildir.
Voila! I just tested this change with Exim4, restarted everything and Evolution now shows me messages. The LAYOUT=fs was correct, and so it was more a matter of getting Exim4 to deliver to ~/Maildir/INBOX .... a little confusing but this was my first time with Exim4 (I've been a sendmail user for a number of years).
Setting up Dovecot LDA with EXIM: http://wiki1.dovecot.org/LDA/Exim
You're probably using procmail or maildrop currently. I don't use either of these, so I'm unfamiliar with their setup WRT maildir. Should be pretty straightforward though.
RoundCube still isn't working but I'm not going to worry about that - Evolution will be cool.
Need more details to help with RC. As long as you can establish an IMAP connection to Dovecot, RC is pretty smart about figuring out where everything is even if you don't explicitly tell it.
Thanks for your help - simply confirming one setting helps.
Heh, I didn't do much, but you're welcome. Are you planning on migrating all the mailboxes from the old server to this new one?
