Ok, I have gotten myself in a bit of a situation with my personal email
server.
I've been running Postfix as a mail server for many years, it's currently
running on a CentOS 5 system. I've also been using pine (or alpine) to read
my email for decades. Well, it appears that Postfix may have a maximum limit
of 2G on mailbox size and I'm bumping up against it. The system itelf has a
1T disk with lots for ree space.
So, I need to overhaul how I handle email (something I've been meaning to to
for years now). I would like to convert to an IMAP style mail handling so I
can use something like Thunderbird for writing ad-hoc mail sorting. Currently
the mailbox and all the "folders" that things are saved in are in mbox
format. That should probably change to Maildir.
This server has been so stable for so many years that I've forgotten most of
what I learned about mail servers since I set it up.
So, I really need some help in figuring out which way to go and how to get
there. Pointers to good documentation appreciated.
It's almost certinly overkill, but I like to run Cyrus as the IMAP server.
Configure Postfix to deliver the mail to Cyrus for new mail, and then use alpine
to copy messages from your old mailbox to the Cyrus mail server and it will
"just work"
What I would do is to install Cyrus without worrying about changing postfix
first. No new mail will be delivered to it, but you can get all the
authentication, multi-domain stuff (if needed) and other things working (and
copy messages there via Alpine for testing), then once you are happy with the
way it's working, change the postfix config to deliver the mail to Cyrus via
LMTP instead of delivering it to local mailboxes. It's probably a one-line
config change or so in Postfix to redirect the mail.
