I'm find out how to reproduce the bug. Config setting contains "location = virtual:/var/mail/virtual" for all users.
1. User1 (with subscribed virtual mailboxes) login and check his virtual dirs. 2. User2 login to server, subscribe to the same virtual mailboxes and checks them. 3. User1 trying to check his virtual mailbox get segmentation fault. > Yes, since each user's virtual mailbox would look different the index > files have to be also separate for each user. Otherwise they'll just > be recreated every time. > > location = virtual:/var/mail/virtual:INDEX=~/virtual > > Or something like that. After I posted my message, I changed location to include INDEX option for testing and server works without any errors(about 4 hours with using virtual mailboxes), so adding INDEX fix the problem. > > > (no debugging symbols found) > .. > > (gdb) bt full > > #0 0xb7f6157c in ??

Maybe I attach core file to wrong binary, I have tried with imap and imap-login - both looks the same.
