i'll attempt also putting these in the bug track thingie this is the result of copying 100 emails (give or take) with imapcopy for reference i used this command to get imapd running without a fork and listening on imap port over the network nc -v -e "/root/test" -l -p 143 /root/test consisted of #!/bin/sh valgrind --tool=massif dbmail-imapd -n and then chmod it 777
