It causes "Server died unexpectedly" when "Maildir/" is not set as /usr/bin/bincimapd argument. The good script (I'm using vmailmgr, but it's the same when not): exec tcpserver -c 100 -u 0 -g 0 \ -l $(hostname) -HDRP \ 0 143 \ /usr/bin/bincimap-up \ --logtype=multilog \ --conf=/etc/bincimap/bincimap.conf -- \ /usr/bin/checkvpw \ /usr/bin/bincimapd Maildir/
Default imap dir is ~/.maildir. If you want to modify it edit /etc/bincimap/bincimap.conf. I've just added the information to the ebuild in bincimap-1.2.7. Thanks for reporting.
