I have a MacPro and a MacBookPro. Same setup for the mail, same accounts. On both macs I use some bundles with Mail.app, MailTag, MailActOn. The only difference is that on the MacPro I have SmapSieve 2.6.6.
Lately, after the System Upgrade to 10.5.2 using Mail.app on the MacPro has become very hectic. When I am typing text Mail.app halts and then later prints what I had blindly added. Also it hangs for a while when I am doing various other things. But is comes back sometimes after several minutes.
I have looked all over the net for similar experience for others and found a few but there are no real answers to the problem yet.
Finally I removed SpamSieve to the Bundles (disabled) folder and the problem is gone it seems. I am very sad to see that this seems to be the culpit because I absolutely love SpamSieve.
Furthermore, while SpamSieve is disabled every single mail goes to the Spam mailbox… I would like an advise so avoid that.
And finally: I am ready to try out any alpha or beta version of SpamSieve that tries to solve this or any other known problem.
Thanks for great program.
