Greetings,
In my installation I have
debian 7.6 dovecot 2.2.13 dovecot-antispamplugin VERSION=2.0
for this enviroment some users cannot get imap connections.
Here below an excerpt the log file.
Jul 09 23:54:07 imap(xx@xxx.co.uk): Panic: file mail-storage.c: line 2158(mailbox_copy): assertion failed: (!ctx->unfinished) ul 09 23:54:07 imap(xx@xxx.co.uk): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x6bb4f) [0x7fd796ccdb4f] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x6bbae) [0x7fd796ccdbae] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fd796c871ee] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0x82519) [0x7fd796fb9519] -> dovecot/imap() [0x40dba4] -> dovecot/imap(command_exec+0x3c) [0x41822c] -> dovecot/imap() [0x417290] -> dovecot/imap() [0x41734a] -> dovecot/imap(client_handle_input+0x115) [0x417605] -> dovecot/imap(client_input+0x72) [0x4179b2] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4e) [0x7fd796cde81e] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xd7) [0x7fd796cdf7f7] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fd796cde8a9] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fd796cde928] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fd796c8c4d3] -> dovecot/imap(main+0x277) [0x40c067] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xfd) [0x7fd7968f5ead] -> dovecot/imap() [0x40c1c5]
for others users imap connection is ok with antispam plugin working fine (antispam_backend = spool2dir)
To enable the imap connections for the unlucky users (with the previous error) I had to remove the anti spam plugin.
Does anybody is experiencing the same errors?
cheers
