Dovcot AntiSpam Errors: plugin.

• [SERVERBUG] failed to send mail --> Thunderbird response when move from ANY to spam and the other way arround.
• [CANNOT] Cannot copy to unsure folder --> Thunderbird response when move from ANY to unsure and the other way arround.
• run program failed with exit code 9 --> debug.log output from antispam

^^ Maybe someone will find this in an archive and saves himself a
_freakn_lot_of_time_ ;)

Hi Nikita Koshikov,

first of all: Thanks for your reply - much apreciated! ;) It wasn't a problem of user rights - that's for sure now. second: @Tom Hendriks: Thanks for the script hint!! ... but still ... very weired - actually extremely weired, cause if I invoke the script it works perfectly - don't ask me why - it's still a mystery to me since there is acutally no difference to how sa-learn is invoked:

script:

server [~]# cat /script.sh #!/usr/local/bin/bash # # - must be bash, cause I was not able to make it log stdout/stderror/stdin into a file ... # - $1,$2,$3,$4 puts all the 4 given parameters/args by dovecot into the sa-learn command. # - make sure to chmod 0777 /DoveDamnAntispam.log # #######################################################################

/usr/local/bin/sa-learn $1 $2 $3 $4 &> /DoveDamnAntispam.log

server [~]#

Antispam part of dovecot.conf:

### Dovecot AntiSpam ### # mail signature (used with any backend requiring a signature) #antispam_signature = X-Spam-Status #antispam_signature_missing = move

antispam_mail_sendmail = /script.sh
#antispam_mail_sendmail = /usr/local/bin/sa-learn
antispam_mail_sendmail_args = --username=%u;--debug;all
antispam_mail_spam = --spam
antispam_mail_notspam = --ham
antispam_mail_tmpdir = /tmp
antispam_spam = Spam
antispam_unsure = Virus
antispam_trash = Trash

I mean there is not a difference at all to me compared to what I've had before?! But what ever - I got it working - that's the most important ;)

So, thanks alot, hey!

Best regards!

Hi Nikita Koshikov,

when I googled for my SERVERBUG which I'm having right now I found your configuration. I'm trying to make use of the antispam plugin as you do. Unfortunately I'm always getting a [SERVERBUG] error mesage with my MTC when I try moving mails. The antispam debug.log doesn't really tell a lot of more:

### Dovecot AntiSpam ###
 # mail signature (used with any backend requiring a signature)
 #antispam_signature = X-Spam-Status
 #antispam_signature_missing = move

 antispam_mail_sendmail = /usr/local/bin/sa-learn
 antispam_mail_sendmail_args = --username=%u;--debug;all
 antispam_mail_spam = --spam
 antispam_mail_notspam = --ham
 antispam_mail_tmpdir = /tmp
 antispam_spam = Spam
 antispam_unsure = Virus
 antispam_trash = Trash

First of all - what OS is this ? BSD ? And how did you install your spamassassin (ports\compiling from source)? Show your local.cf file (/etc/mail/spamassassin or /usr/local/etc/mail/spamassasin).

After reading perldoc Mail::SpamAssassin::Conf add to your local.cf for debugging: bayes_file_mode 0777 bayes_path /tmp/.spamassassin/bayes

Create folder /tmp/.spamassassin and set permitions 777. Restart spamd with dovecot and try it.

...

I also read through the sa-learn script but wasn't able to figure out where this number 9 is coming from ;/ ... SIGKILL 9 Term Kill signal - but where from ?!

sa-learn has lots of die() function, this should be enough for raising SIGKILL.

...

Do you maybe have any idea? I tried different Dovecot versions already - alwys the same ... Might there maybe somethign wrong with my syntax?

Any way - thanks a lot in advance& regards

If you stuck after all, remember that sa-learn has -D key, it generate tons of output. Create wrapper and run sa-learn with -D keyword from dovecot, save result and have fun.

unfortunately I still wasn't able to figure out what's going on. I tried to debug the sa-learn perl script and I wasn't able to find any hint to that code. (I'm not a beginner) But I guess that this is not an issue of sa-learn. Why? Because sa-learn does as I asked it to. sa-learn writes everything into the SQL DB as wanted - but the mail is not being copied to the destination plus the dovecot server returns the old known [SERVERBUG] message to Thunderbird. I obviously also tried:

server [~]# sa-learn --username=admin@mydom.com --spam /var/mail/admin/.Spam/ Learned tokens from 0 message(s) (2 message(s) examined) server [~]#

"Learned tokens from 0" because it has learnd from Dovecot antispam already. If I reset SQL values it would learn again.

Here is my debug.log output again.

Those are my Antispam options from dovecot.conf:

[...] ### Dovecot AntiSpam ### # mail signature (used with any backend requiring a signature) #antispam_signature = X-Spam-Status #antispam_signature_missing = move

  antispam_mail_sendmail = /usr/local/bin/sa-learn
  antispam_mail_sendmail_args = --username=%u --debug all

anitspam_blah_args is a semicolon separated list, no spaces (I thought

  antispam_mail_spam = --spam
  antispam_mail_notspam = --ham
  antispam_mail_tmpdir = /tmp
  antispam_spam = Spam
  antispam_unsure = Virus

[...]

Even --debug all doesn't help a thing ;( I tried my luck enabeling all this Dovecot debug knobs:

## ## Logging ## mail_debug = yes auth_verbose = yes auth_debug = yes auth_debug_passwords = yes log_timestamp = "%b %d %H:%M:%S " syslog_facility = mail

... didn't help ... - dovecot's log didn't tell me anything new - no error nothing after the Serverbug happend ... ;(

I really don't know where to debug anymore ;( Therefore, I would _really_ - out of all my frustration - appreaciate your help (cause this issue is now bothering me now for more than two weeks now already

• without any little peace of success)

Thanks& Regards

Thanks for your reply. I tried that one as well - unfortunately that didn't really help a lot. Debug now looks a bit different than before: (Ofcourse did I try it without the debug option at all as well - but with the same result.)

But unfortunately there is no more debug as I was hoping of sa-learn. I also tried using different Dovecot versons already - but with the same result - they all give my MTC a SERVERBUG when I try to move mails with the help of the antispam plugin.

What happens when you write a small shell wrapper and put that in place of sa-learn, which calls sa-learn, and let it save the input (arguments as produced by the plugin) and output of sa-learn to a temporary file?
