Hi all.

I am trying to get dovecot (1.0.rc17) running with antispam plugin.

I have created another backend, which executes "sa-learn" from spamassassin's arsenal. The backend is modeled after sendmail backend.

But I can't seem to get the plugin working wit either my backend or signature-log.

This is my ".config": DOVECOT=/usr/src/dovecot-1.0.7 DOVECOT_VERSION=1.0 BACKEND=spamassassin-exec INSTALLDIR=/usr/lib/dovecot/modules/imap/ PLUGINNAME=antispam

This is how I make the plugin: make && make install && chmod 644 /usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so

Since Ubuntu server does not come with dovecot sources, I have downloaded dovecot-1.0.7 and put it in /usr/src. As far as I understand, only the headers are needed, so this should not be the cause of the crash (if the headers hadn't changed).

When invoked from dovecot process, the "imap" dies with signal 11.

When running: strace /usr/sbin/dovecot --exec-mail imap

This is how it ends: etdents64(8, /* 14 entries */, 4096) = 592 getdents64(8, /* 0 entries */, 4096) = 0 open("/usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so", O_RDONLY) = 9 read(9, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\340\21"..., 512) = 512 fstat64(9, {st_mode=S_IFREG|0644, st_size=19252, ...}) = 0 mmap2(NULL, 16148, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 9, 0) = 0xb7f29000 mmap2(0xb7f2c000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 9, 0x2) = 0xb7f2c000 close(9) = 0 close(8) = 0 stat64("/var/mail/mailboxes/boky/Maildir/subscriptions", 0xbfc17d2c) = -1 EACCES (Permission denied) lstat64("/var/mail/mailboxes/boky/Maildir/cur", 0xbfc17c3c) = -1 EACCES (Permission denied) write(2, "imap(boky): ", 12imap(boky): ) = 12 write(2, "Error: ", 7Error: ) = 7 write(2, "lstat(/var/mail/mailboxes/boky/M"..., 69lstat(/var/mail/mailboxes/boky/Maildir/cur) failed: Permission denied) = 69 write(2, "\n", 1 ) = 1 open("/etc/localtime", O_RDONLY) = 8 fstat64(8, {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 fstat64(8, {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7de2000 read(8, "TZif\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0\0\0\6\0"..., 4096) = 696 close(8) = 0 munmap(0xb7de2000, 4096) = 0 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Process 4707 detached

antispam plugin was downloaded from: http://git.sipsolutions.net/?p=dovecot-antispam.git;a=snapshot;h=HEAD;sf=tgz

Please advise me n next steps; I'm just a beginner with debugging C/C++.

Thank you all. Boky
