IMAP/POP3 specifically have been switched from Cyrus to Dovecot. Next weekend I'll likely upgrade the SMTP server, which will remove the last vestigages of any Cyrus gear around.

Webmail was upgraded mildly. The filter stuff, lots of new code if you're accessing it from SquirrelMail (webmail). Things appear to be working.

Hopefully nobody noticed any folder changes - I've set the new software up to expose mailboxes in a compatible way.

Unix users will find their mail in $HOME/Maildir . IF you use procmail, your procmail rules have been updated. I hope to get more documentation up in the next week on what you can do with it (including storing and pop3/imap accessing mailbox format, if you so choose).

My contact info is listed via whois; or you can use:

This is a preemptive change of software to something more easy for me to manage, and consequently, easier to upgrade during emergencies.)

POP3 users: I expect you guys to have no change.

IMAP users: You MAY need to tell your mail client to rescan the folders on the server. You MAY need to actually remove the account, and re-add it. My hope is you don't notice at all.

IMAP users with big folders (100+ megs): You'll probably see greater impact. When I do cut you over, I'll have your most recent mail copied, and your INBOX synced. The catch-up sync may happen after the cutover. IF this is the case ,you may notice that if you deleted a message that it gets resynced from the old server.

SquirrelMail users: I expect no change.

Unix users only: When things are done, pop/imap storage will be moved from the cyrus private directory into your personal $HOME/Maildir/. Contact me if you want mbox format.

Frequently Asked Questions

Why are you doing this?

To simplify the mail server configuration, in the event of a security need to upgrade things in an emergency. My time is limited with my busy work schedule. With the changes I am making, security upgrades should cost me only a few minutes if/when needed. The previous setup was too hard to build and had too many dependencies.

Is the mail server insecure right now?

No. I'm doing this as a preventive measure. The newer software is trivial to upgrade the various components.

I hate Maildir format. (unix)

If you were using pop/imap, you were using it and just didn't notice it.

I want to use mbox format. (unix)

Poke jfesler. The new software will be able to serve both formats.

What about my procmail files? (unix)

I'll translate them once during the cutover.

What about my SquirrelMail filters (webmail)

They should still work when this is done; this is one of the things I am testing this weekend. I may have to log in with your account once to force the filters to be pushed. This FAQ entry should update later as I know more.
