For the last several years, I’ve run a Courier-IMAP mail server for all of the mail for this site, Kineticode, Strongrrl and other domains. We mainly used Mail.app on Mac OS X to communicate with the server, and it worked really well. Today, Julie has over 3 GB of mail data, and I have around 1.5 GB, all managed via IMAP.
Recently, I decided it was time to move the mail elsewhere. I’ve been meaning to do it for a while, primarily because the server I was using is now used for the Bricolage project, and because I never set up any spam filtering. Julie was suddenly getting 100s of spam messages in her inbox. (It really didn’t help that she was still using Panther.) So on the advice of a good friend who had been evaluating various mail services–and who for now shall go nameless and therefor blameless–I moved all of our mail to FuseMail.
At first this seamed like a pretty good solution. Our spam rates went way down, I could set up unlimited mail lists, aliases, and forwards, and there was a migration tool that automated moving all of our existing mail from the old IMAP server to the new one. There were some glitches with the migration tool, but in the end all of our mail was moved and in tact.
But that’s when I started to notice the issues. To summarize:
- Mail put into the “Sent Items” folder by Mail.app was marked as unread. This didn’t happen on the old server, and apparently has something to so with how FuseMail names the sent folder: “Sent Items” rather than “Sent Messages.”
- Mail.app is syncing constantly. Even once it had successfully synced the all of our email in all of our IMAP folders (which took days, it is syncing all the time, to the extent that I am sometimes waiting for up to a minute to read a mail when I double-click it, because there are all these other threads doing stuff and taking up all the resources. It can take several minutes for mail I’m sending to be sent (though that might be a delay in Mail.app copying the message to the Sent Items folder rather than the actual sending).
- Deleting mail takes forever! This is probably the same issue as the syncing problem, but when I delete 1000s of messages from my Junk mail folder, it runs forever, and all other activities are delayed eve further. It turns out to be much more efficient to empty the Junk and Deleted Items folders using the webmail interface. And even then, Mail.app can take a while to delete locally-cached items from the folder when it syncs.
- Suddenly, Julie is getting a lot less spam. She went from several hundred messages showing up in her Junk mailbox a few days ago to just five on Friday and two yesterday–one of which was a false positive). As she had been expecting a message from someone that she never got, this naturally made her very suspicious. Where is all the spam? Is she getting all of her mail?
- Since FuseMail uses a mailbox named “Sent Items” instead of the traditional “Sent Messages” for all sent mail, I asked if they could move the 1.8 GB of messages from Julie’s Sent Messages to their Sent Items, since Mail.app would just choke on such a task. Though my request was escalated to the FuseMail developers, the answer came back “no.” Which I guess means that they’re not using Maildir, because in that case it would be a cinch, n’est pas?
- Backups are not really feasible. Of course FuseMail has its own backup regimen, but if I ever want to move elsewhere or deal with some sort of catastrophic failure, I want my own backups. There is no rsync service available for this (remember: no maildir), so I have to use the IMAP interface. I’ve been trying for the past two weeks to get Offline IMAP to back up all of Julie’s and my mail, but it keeps choking. It gets a little further every time I run it; eventually it will get it all. But this only allows me to backup those accounts for which I happen to have a password. I have accounts set up for a few other users, but don’t have access to their passwords, so I can’t back them up. This does not make for very good support for corporate backup and retention policies.
- Mail forwarded by FuseMail has its
Return-Pathheader modified. This made RT break until I hacked it to ignore that header (which is its by-default preferred header for identifying senders.
So I’m pretty fed up. It took me a week to get all of our mail on FuseMail, and now I’m looking at moving it off again (once OfflineIMAP finishes a full sync). Grr. I’m considering finding a virtual host somewhere and setting up my own IMAP server again, but then I have the spam problem again. So then I could use a forwarding service like Pobox, or I can set up my own spam filtering (something I had hoped never to get into managing myself). My old IMAP server required very little maintenance, which was nice, but then the span filtering stuff always seemed daunting. Don’t you have to update things all the time?a
But before I go off and do something else, and unlike before I moved to FuseMail, I wanted to get an idea what other folks are doing? Do you use IMAP? Do you use it to manage a shitload (read: Gigabytes) of mail? Do you get very little spam and still get all of your valid mail? Are IMAP folder maintenance actions fast for you (in Mail.app in particular)? Are you paying a not-unreasonable amount of money for your setup? If you answered yes to all of these questions, please, for the love of all that is good in this world, tell me how you do it. I’m looking for something that I don’t have to work very hard to maintain (hence my original attempt to have some company that specializes in this stuff do it), but I’ll do what I have to to make this thing right. So how do you make it right? And if I have to run my own server, where should I host it that won’t cost me an arm and a leg?
Thanks for your help!
