imap segfaults when using antispam plugin, and moving mail to an 'unsure' folder.
I put up a question on serverfault first, which has the details, including a stack trace: http://serverfault.com/questions/713687/dovecot-antispam-error-storing-mail . Details also copied below. Is this a known bug? If I built dovecot from source rather than using the Ubuntu 14.04 packages, would I expect that to help? Are there any configuration details that might be relevant? (dovecot -n output shown Any help much appreciated. Andrew McNaughton Details on the serverfault page repeated below, plus a little more. ----------------------------------------------------- Ubuntu 14.04.3 x86_64 Running inside lxc-docker 1.7.0 dovecot-imapd 1:2.2.9-1ubuntu2 dovecot-antispam 2.0+20130822-2build1 Filesystem is via docker, so aufs is involved, and under that on the host systems is ext4 ----------------------------------------------------- I know mail is not supposed to be moved into a mailbox of type 'unsure'. The server should refuse this action. What actually happens though is that the imap process throws an error and dies: Aug 12 17:53:07 255c7fc2d2f0 imap: antispam: mailbox_is_unsure(Review-Classification): 1 Aug 12 17:53:07 255c7fc2d2f0 dovecot: imap(user at example.com): Panic: file mail-storage.c: line 2141 (mailbox_copy): assertion failed: (!ctx->unfinished) Aug 12 17:53:07 255c7fc2d2f0 dovecot: imap(user at example.com): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x5e271) [0x7f718e7dd271] -> /usr/lib/dovecot/libdovecot.so.0(+0x5e34e) [0x7f718e7dd34e] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f718e798a9e] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x7196f) [0x7f718eab896f] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_move+0x15) [0x7f718eab8985] -> dovecot/imap(+0xded5) [0x7f718ef84ed5] -> dovecot/imap(command_exec+0x3c) [0x7f718ef8f6dc] -> dovecot/imap(+0x176cf) [0x7f718ef8e6cf] -> dovecot/imap(+0x17785) [0x7f718ef8e785] -> dovecot/imap(client_handle_input+0x125) [0x7f718ef8eaa5] -> dovecot/imap(client_input+0x75) [0x7f718ef8ee35] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7f718e7ed247] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7f718e7edfd7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f718e7ecde8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f718e79dc93] -> dovecot/imap(main+0x2c4) [0x7f718ef832f4] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f718e3dbec5] -> dovecot/imap(+0xc460) [0x7f718ef83460] Aug 12 17:53:07 255c7fc2d2f0 dovecot: imap(user at example.com): Fatal: master: service(imap): child 58 killed with signal 6 (core dumped) ----------------------------------------------------------------------- root at 8ec9579667fc:/# gdb /usr/lib/dovecot/imap /tmp/61 GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.

imap segfaults when using antispam plugin, and moving mail to an 'unsure' folder.
I've had no responses to this bug report. Does anyone have any ideas on how I can move it forward?
