I managed to upgrade my mail server from RH9 to FC2 by the seat of my pants (involving, amongst other things, a hung boot process in RH9 that just made me decide to go ahead and do it on the main drive, but that's another long story). I've now installed dovecot, since the uw-imap and uw-ipop3 are now gone. I've got it up and running, and it seems to work, but there's an interaction problem with Evolution (1.4.6). I've got the following in the dovecot.conf file: # Dovecot can notify client of new mail in selected mailbox soon after it's # received. This setting specifies the minimum interval in seconds between # new mail notifications to client - internally they may be checked more or # less often. Setting this to 0 disables the checking. # NOTE: Evolution client breaks with this option when it's trying to APPEND. mailbox_check_interval = 0 ...which I set specifically because I do use Evolution (at home). However, Evolution seems to hang when connecting, and this seems to hang the server for any other instance of this userID logging in and/or sending mail. Restarting dovecot and sendmail don't fix this problem - any suggestions on where to start? -Don
