No, I can't get it to work, either. I'm still using QT Mail, which works fine.
"Error logging into IMAP server" ... have asked about this bug in various threads and the only response I've received is that it
should work. In other words, it's functional in theory but not in practice.
KDE/PIMpi is being updated quite regularly lately, so it's possible we'll see a fix for this .Mac IMAP glitch eventually. Then again, the last version (2.0.3) kept crashing on my regular POP3 account. Best thing to do is contact
zautrix, who I think is the primary developer for the Z port of the suite, and fill him in on the issue.
