Maybe the packager set some compiler options explicitly there.

The problem with your backtrace is that: #0 mail_get_physical_size (mail=0x8135db8, size_r=0x0) at mail.c:100 - size_r should never be NULL here. - mail is set here, but #1 0xb7e575c5 in quota_check (t=0x8135db8, mail=0x0) at quota- storage.c:148 qt = (struct quota_transaction_context *) 0x0 ret = too_large = 8 - mail is NULL here. So is it really set or isn't it set? This inconsistency probably gets fixed by not using -O2. - ret = is also caused by -O2 # export CFLAGS="-g3 -O0" I don't know if this is supposed to work when compiling debian packages. If it doesn't get rid of the , then I guess it's not being used. PGP.sig Description: This is a digitally signed message part

Re: [Dovecot] Error using antispam plugin
Well Finally i found the error. It look like antispam is not compatible with quota plugin. mail_plugins = quota imap_quota autocreate antispam If i remove quota and imap_quota plugins from imap protocol, everything works fine and the message is saved in sent folder. mail_plugins = autocreate antispam If i enable again the plugins, the error happens again.

Re: [Dovecot] Error using antispam plugin
Hi again Testing with Dovecot 1.1RC7, and antispam plugin 31/05/2008, 18:00, the problem persists. The error ocurrs when Evolution/Thunderbird tries to save the message in the Sent folder (the message is sent and received by the recipient correctly). If i disable antispam plugin from IMAP protocol everything works fine. Sent folder has been autocreated and autosubscribed using the autocreate plugin. With plugin autocreate disabled and folders subscribed manually the problem persists. Now i have compiled dovecot-antispam plugin with the -g3 option in CFLAGS. What to do now? The errors shown by dovecot are these: dovecot: May 31 19:49:24 Error: child 16929 (imap) killed with signal 11 dovecot: May 31 19:49:24 Error: child 16933 (imap) killed with signal 11 dovecot: May 31 19:49:25 Error: child 16936 (imap) killed with signal 11 dovecot: May 31 19:49:26 Error: child 16940 (imap) killed with signal 11 In syslog, antispam plugin logs this (compiled with DEBUG_VERBOSE=1): May 31 19:51:33 pdc-server imap: antispam: plugin initialising May 31 19:51:33 pdc-server imap: antispam: "Trash" is trash folder May 31 19:51:33 pdc-server imap: antispam: "Junk" is spam folder May 31 19:51:33 pdc-server imap: antispam: mail backend spam address -r May 31 19:51:33 pdc-server imap: antispam: mail backend not-spam address -k May 31 19:51:33 pdc-server imap: antispam: mail backend sendmail /usr/bin/spamassassin May 31 19:51:33 pdc-server imap: antispam: mail backend tmpdir /tmp repeated for every child error.

Re: [Dovecot] Error using antispam plugin
No idea how to add the -g3 option to compile. Once done, how and where is the gdb generated? I would need detailed help to do this. I know that it is known to not work, but if nobody uses it, then it will never work. I think this plugin is great, a great way to classify SPAM without difficult instructions for the final users. I will use the plugin with SpamAssassin, not DSPAM.

Well, compile with -g3 and attach gdb. It's known to not work, and I never said it work would, in fact, the defconfig file you edited clearly states: # Dovecot version to build against DOVECOT_VERSION=1.0 #DOVECOT_VERSION=1.1# CURRENTLY BROKEN No further comments. johannes signature.asc Description: This is a digitally signed message part
