Hi all,

Trying to use SpamAssassin with Postfix using spamd: 
https://cwiki.apache.org/confluence/display/SPAMASSASSIN/IntegratedSpamdInPostfix

Unfortunately emails are not going to my inbox processed by 
SpamAssassin. Postfix seems to be calling SpamAssassin correctly, as I 
see this in my Postfix log:

Nov 04 03:33:05 master postfix/pipe[10769]: 98AB01261F7: 
to=<[email protected]>, relay=spamassassin, delay=0.27, 
delays=0.25/0.01/0/0.02, dsn=2.0.0, status=sent (delivered via 
spamassassin service)

However, emails arrive in my inbox unchanged, with no X-Spam headers.

I see the following errors in my syslog corresponding to receiving an 
email that's processed by SpamAssassin:

Nov  4 03:33:05 master mail.warn spamd[13148]: spamd: error: Bad arg 
length for Socket::unpack_sockaddr_in, length is 28, should be 16 at 
/usr/lib/perl5/core_perl/Socket.pm line 857.
Nov  4 03:33:05 master mail.warn spamd[13148]:  , continuing at 
/usr/sbin/spamd line 1419.
Nov  4 03:33:05 master mail.info spamd[13144]: prefork: child states: II

I've tried looking up this error message but don't see it anywhere on 
the internet.

SpamAssassin version:
SpamAssassin version 3.4.6
   running on Perl version 5.38.2

Platform: Alpine Linux 3.20.3

Postfix: version 3.9

Attached are my /etc/postfix/master.cf and 
/etc/mail/spamassassin/local.cf, let me know if there's any other config 
files that need to be shared. I appreciate any help/responses.

Thanks,
revsuine

###########################################################################

#    A 'contact address' users should contact for more info. (replaces
#    _CONTACTADDRESS_ in the report template)
# report_contact [email protected]


#   Add *****SPAM***** to the Subject header of spam e-mails
#
rewrite_header Subject [SPAM]


#   Save spam messages as a message/rfc822 MIME attachment instead of
#   modifying the original message (0: off, 2: use text/plain instead)
#
report_safe 0


#   Set which networks or hosts are considered 'trusted' by your mail
#   server (i.e. not spammers)
#
# trusted_networks 212.17.35.


#   Set file-locking method (flock is not safe over NFS, but is faster)
#
# lock_method flock


#   Set the threshold at which a message is considered spam (default: 5.0)
#
required_score 5.0


#   Use Bayesian classifier (default: 1)
#
use_bayes 1


#   Bayesian classifier auto-learning (default: 1)
#
bayes_auto_learn 1


#   Set headers which may provide inappropriate cues to the Bayesian
#   classifier
#
# bayes_ignore_header X-Bogosity
# bayes_ignore_header X-Spam-Flag
# bayes_ignore_header X-Spam-Status


#   Whether to decode non- UTF-8 and non-ASCII textual parts and recode
#   them to UTF-8 before the text is given over to rules processing.
#
# normalize_charset 1

#   Textual body scan limit    (default: 50000)
#
#   Amount of data per email text/* mimepart, that will be run through body
#   rules.  This enables safer and faster scanning of large messages,
#   perhaps having very large textual attachments.  There should be no need
#   to change this well tested default.
#
# body_part_scan_size 50000

#   Textual rawbody data scan limit    (default: 500000)
#
#   Amount of data per email text/* mimepart, that will be run through
#   rawbody rules.
#
# rawbody_part_scan_size 500000

#   Some shortcircuiting, if the plugin is enabled
# 
ifplugin Mail::SpamAssassin::Plugin::Shortcircuit
#
#   default: strongly-whitelisted mails are *really* whitelisted now, if the
#   shortcircuiting plugin is active, causing early exit to save CPU load.
#   Uncomment to turn this on
#
#   SpamAssassin tries hard not to launch DNS queries before priority -100. 
#   If you want to shortcircuit without launching unneeded queries, make
#   sure such rule priority is below -100. These examples are already:
#
# shortcircuit USER_IN_WHITELIST       on
# shortcircuit USER_IN_DEF_WHITELIST   on
# shortcircuit USER_IN_ALL_SPAM_TO     on
# shortcircuit SUBJECT_IN_WHITELIST    on

#   the opposite; blacklisted mails can also save CPU
#
# shortcircuit USER_IN_BLACKLIST       on
# shortcircuit USER_IN_BLACKLIST_TO    on
# shortcircuit SUBJECT_IN_BLACKLIST    on

#   if you have taken the time to correctly specify your "trusted_networks",
#   this is another good way to save CPU
#
# shortcircuit ALL_TRUSTED             on

#   and a well-trained bayes DB can save running rules, too
#
# shortcircuit BAYES_99                spam
# shortcircuit BAYES_00                ham
