With the move to my new web host, I finally have the luxury of good, fast IMAP email again (thank you!). I had been doing the Gmail thing for the past few months using the very awesome MailPlane, but even as much as the app rocks, it still wasn’t quite what I was looking for in the way of doing mail.
Though I touted GyazMail as the mail app to have a while back, I’ve secretly harbored a desire to use my first love, Mail.app. There’s something about it that I find gets me where I want to be the quickest. But I digress. This post isn’t about which email reader is better…
Instead, this post is intended to help others who may have run into the same problem I had. Every so often when I’d launch Mail 3.1 in Leopard, or just at other times for no reason, the application would become totally unresponsive. Mail would still arrive, but I couldn’t do much more with it than move the main window around on my screen. I was almost as though the application was frozen, but not quite. Obviously it was doing something very resource intensive to become that unresponsive.

After some rooting around, I think I discovered the problem. By setting the “Add invitations to iCal” option in the General preference of Mail to “Never”, all of my freezes have suddenly disappeared. This may or may not help someone else who’s having the same issue. But for me, it did the trick. Your mileage may vary.
[Update] I’ve also noticed that GrowlMail doesn’t seem to be playing nicey-nice with Mail under Leopard. When I logged out or restarted, logged back in, and launched Mail, it would freeze up as GrowlMail thought about displaying a notification for each message, quite slowly.
If you have GrowlMail installed, and are experiencing freezes in Leopard Mail, try turning it off (Mail > Preferences > GrowlMail). Post a comment if that helps (or doesn’t). So far, it seems to solve the problem for me.
Oh, and I got rid of MS Office completely too. That might have some bearing, or it might not. I’m using iWork ’08 for that kind of stuff now.






Hey,
I stumbled (googled) here looking for answers tonight, and switching that setting off has certainly improved things. I have a bunch of gmail via IMAP, and my “litle snitch” was showing a huge amount of IMAP activity in mail.app all the time.
After a qhile I’d just have to restat, and sometimes force quit.
Since turning off that feature, the snitch is quiet, and mail seems more responsive. It could be wishful thinking, but for tonight I’m very grateful you posted this.
Thanks!
Another thing I just figured out is this….. if you’re using IMAP for your mail, in account preferences > mailbox behaviours, make sure you uncheck the “save drafts on server” option. I found this really helped a lot. No more freezes

Wow! Thank you all. Huge help.
