Did you consider that this might be a bug instead of a configuration error?

Dovecot version is 2.2.13. It crashes on every incoming mail as long as
the antispam plugin is activated.

As far as I know sa-learn requires a filename at command line, therefore
http://wiki2.dovecot.org/Plugins/Antispam spools the message to a file
before. Could you try this script? Maybe you can use "-" as filename or
something like that.

antispam plugin crash
Hi, the dovecot antispam plugin crahses here on a nullpointer dereference in antispam_copy() at mailbox.c The crash tracks back to a call of antispam_classify_copy(asms->box_class, asmb->box_class) At that point in time asmb is set to 0x0, causing the process to crash with SIGSEGV. Regards, Thomas GDB output: Program received signal SIGSEGV, Segmentation fault. antispam_copy (ctx=0x14ed9f0, mail=0x14c6cc0) at mailbox.c:107 107 enum mailbox_copy_type copy_type = (gdb) bt #0 antispam_copy (ctx=0x14ed9f0, mail=0x14c6cc0) at mailbox.c:107 #1 0x7fdadb627fcd in mailbox_copy () from /usr/lib64/dovecot/libdovecot-storage.so.0 #2 0x7fdada6cdba0 in act_store_execute () from /usr/lib64/dovecot/libdovecot-sieve.so.0 #3 0x7fdada6c59d9 in sieve_result_execute () from /usr/lib64/dovecot/libdovecot-sieve.so.0 #4 0x7fdada6d4a2a in sieve_execute () from /usr/lib64/dovecot/libdovecot-sieve.so.0 #5 0x7fdada9212cb in lda_sieve_deliver_mail () from /usr/lib64/dovecot/lib90_sieve_plugin.so #6 0x7fdadb8cae1a in mail_deliver () from /usr/lib64/dovecot/libdovecot-lda.so.0 #7 0x00405ebd in client_input_data_handle () #8 0x7fdadb34e9bf in io_loop_call_io () from /usr/lib64/dovecot/libdovecot.so.0 #9 0x7fdadb34f8b7 in io_loop_handler_run_internal () from /usr/lib64/dovecot/libdovecot.so.0 #10 0x7fdadb34ea29 in io_loop_handler_run () from /usr/lib64/dovecot/libdovecot.so.0 #11 0x7fdadb34eaa8 in io_loop_run () from /usr/lib64/dovecot/libdovecot.so.0 #12 0x7fdadb2fe803 in master_service_run () from /usr/lib64/dovecot/libdovecot.so.0 #13 0x00404995 in main () (gdb) p asms $3 = (struct antispam_mailbox *) 0x0
