Hi,

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 at 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
    antispam_mail_spam = --spam
    antispam_mail_notspam = --ham
    antispam_mail_tmpdir = /tmp
    antispam_spam = Spam
    antispam_unsure = Virus
    antispam_trash = Trash
[...]

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
