Hello,
Running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam, i
finally upgraded to dovecot 2.X.
I'm running dovecot 2.2.6, dspam 3.10.2-r1 and
dovecot-antispam-2.0_pre20130429.
My DSPAM configuration hasn't changed between dovecot 1.X and 2.X.
When i'm moving a mail to or from the Spam folder, Igot this error in my
logs :
Nov 14 10:33:25 srv1 dovecot: imap(ghilt at shadowprojects.org): Debug:
dspam error:7751 prefix=imap(ghilt at shadowprojects.org):
Nov 14 10:33:25 srv1 dovecot: imap(ghilt at shadowprojects.org): Debug:
executing /usr/bin/dspam failed: 13 (uid=1001, gid=12)
Nov 14 10:33:25 srv1 dovecot: imap: Error:
Nov 14 10:33:25 srv1 dovecot: imap: Error:
uid 1001 is user vmail (dovecot is running under vmail)
gid 12 is group mail (vmail is a member, with
mail,postfix,dspam,dovecot,apache)
I enabled DSPAMdebug mode and when i move the mail, i don't see anything
in the logs, meaning that dspam isn't called at all.
Enabling debug in dovecot doesn't give me more informations.
Here's my dovecot plugins settings :
plugin {
#setting_name = value
# Selects the specific backend to be used for spam system training
antispam_backend = dspam
# Specifies whether to allow appending mails to the spam folder
# from the unknown source. Optional, default = NO.
antispam_allow_append_to_spam = NO
# Specifies whether to skip the leading "From " line of the mail
# piped to the backend processor. Optional, default = NO.
antispam_skip_from_line = NO
# semicolon-separated list of spam folders
antispam_spam = Spam
# semicolon-separated list of Trash folders (default unset i.e.
none)
antispam_trash = Trash
# semicolon-separated list of unsure folders (default unset
i.e. none)
#antispam_unsure =
# mail signature (used with any backend requiring a signature)
antispam_signature = X-DSPAM-Signature
# specifies what to do if the signature header is missing. Possible
# values: "move" (move the mail silently without training), "error"
# (display an error stating that the signature header is missing).
# Optional, default = "error".
antispam_signature_missing = error
# specifies the path to the dspam client binary.
# Optional, default = "/usr/bin/dspam".
antispam_dspam_binary = /usr/bin/dspam
# list of command line arguments to the dspam binary. Must include
# one "%%s" in order to be replaced with the signature value.
# Optional, default = "--source=error;--signature=%%s".
antispam_dspam_args =
--user;%u;--deliver=;--source=error;--signature=%%s
# command line argument to specify that mail should be reclassified
# as SPAM. Optional, default = "--class=spam".
antispam_dspam_spam = --class=spam
# command line argument to specify that mail should be reclassified
# as not SPAM. Optional, default = "--class=innocent".
antispam_dspam_notspam = --class=innocent
# specifies the mail header name to derive the classification
result.
# Optional, default = NONE.
antispam_dspam_result_header = X-DSPAM-Result
# specifies the list of classification results to avoid retraining
# for. Optional, default = NONE.
#antispam_dspam_result_blacklist = Virus;Blocklisted;Blacklisted
}

DSPAM binary is owned by dspam (chmod u+s) :

And all the necessary users are trusted by DSPAM :
Trust root
Trust dspam
Trust apache
Trust mail
Trust mailnull
Trust smmsp
Trust daemon
Trust vmail
Trust dovecot
Trust postfix
Any idea ?
Thanks,
