Re: [Dovecot] antispam plugin / mailtrain backend: t_pop() leak & killed with signal 6

Leaked a t_pop() call in I/O handler 0x805b350

Raw backtrace: imap [0x80ad741] -> imap [0x80ad65c] -> imap(io_loop_handler _run+0x1ce) [0x80b35ce] -> imap(io_loop_run+0x28) [0x80b29a8] -> imap(main+0x5a0) [0x8063590] -> /lib/tls/i686/cmov/libc.so.6(__lib c_start_main+0xc8) [0xb7e37ea8] -> imap [0x8055e31]

child 18478 (imap) killed with signal 6

Cause is, if sendmail fails with an exit code != 0, the function returns with -1 immediately skipping the t_pop() before the end of the function.

See attached diff.

Merged, thanks.
