Tim, maybe you missed something, so I repeat: 1) Evolution crashed constantly while I was picking main from 4 accounts evey minute in Fedora7. Then I made clear the 4 accounts correspond to 2 servers in my LAN. No external ISPs! That used to work fine (4 picking-ups each every minute) in FC6. Solution: pick up mail every 15/30 min. Worked like a charm. But Evo gets slow once in a while. 2) Anyway, if an ISP blocks constant pop3/imap/(s) email picking, is no reason for Evolution to horribly crash and slow the pc. > Why is your client using heavy CPU checking for mail? - My guess is that > spam assassin is looking at it coming through, checking against a > plethora of rules.

Right and thanks 4 the tip, Ive supposed the same, and a week ago added this crontab rule, just to try what happens: 0 0 * * * /bin/rm /home/rodolfoap/.spamassassin/* Anyway, evolution got slow a couple of times again. Tried rpm -e spamassassin, but it sez evolution needs him. haha.... I tried switching to thunderbird, but I perl-export evolution's contacts BerkleyDB to my LDAP server, and sync Evo contacts/tasks/memos with my Palm, which really works GOOD. Hope the bug get fixed soon.
