debug: config: read file /etc/mail/spamassassin/local.cf debug: DCCifd is not available: no r/w dccifd socket found.
In that spamassassin config file I have (I tried without this entry and get same thing):
dcc_dccifd_path /var/dcc
In the /var/dcc I have:
srw-rw-rw- 1 root root 0 Feb 9 18:01 dccifd
Try this instead:
dcc_dccifd_path /var/dcc/dccifd
It's rather unfortunate that the SA config option naming convention has no consistency whatsoever for the use of the word "path".
Sometimes options named path are expecting a path with no filename (dcc_path), sometimes a path plus partial filename (bayes_path), and sometimes, a full path with filename.
dcc_dccifd_path actually expects a full path+filename, although the documentation fails to make this clear, and actually seems to reinforce the concept that this option is a directory.
Tsk. Tsk. Strike one for the manpage team, and strike one for the option naming convention team :)
