Mac OS X 10.4.3 breaks Mail.app
So, I finally installed Mac OS X 10.4.3 last night, but with little success- Mail.app is now useless to me.
When I fired up Mail.app this morning, none of the rules would actually work, I couldn’t edit the rules and I couldn’t create new rules.
Time to switch to Thunderbird.
Update: It looks like it was either MailTags or Mail Act-on, because after uninstalling those, everything seems fine. I’ll have to see if there’s an update available.
Update 2: I was write, it was Mail Act-on. Apparently I’d missed a critical update. All is fine now. Nothing to see here.

But… but… you’re using Thunderbird now, eh? ;-)

remi-
I don’t have time to switch.
5 email accounts + 30 filtering rules + 15 act-on rules + schoolwork + a job = no time

Yep, I had the same rules problem. Interestingly I only had MailTags installed, and on uninstall all is well again.
Thank God!

Actually the problem was with MailTags.
Version 1.1 was release November 2 and that took care of compatability problems with Mail in 10.4.3
Also Version 1.1 added a host of news features. (such as multiple keywords etc)

Hey bro,
I had this problem with MailTags but didn’t know what the answer was and had just been dealing with. I stumbled on to your blog and found the answer. THANK YOU!!

Seems the same is true w/10.4.5? I am new to Mac OS X, so 10.4.5 is all I have ever used, but I installed MailTags and shortly after, Mail.app began crashing. Removing MailTags, all works fine, no crash in several days now.
I **really** like MailTags, I hope the problem is fixed soon.
