Hello,
I've just spent the day trying to come up with another solution. My reasoning was that everything should be able to be scanned.. but the problem is with the filter in that it doesn't know what type of emails it's dealing with, which is why it's blindly saving things.
The idea is simple: tell the filter what type of email it's dealing with, so it can more intelligently figure out where it's supposed to go. The only way I was able to manage this was by adding extra headers to the email before spamd time, so that the filters could see them (headers added at domain filter time are not seen by the filter).
This is just another possibility, and is likely still very rough, but provides another option for admin's should they need it.
1) Make your spamcheck director look like this
Code:
# Spam Assassin
spamcheck_director:
driver = accept
condition = "${if and { \
{!def:h_X-Spam-Flag:} \
{!eq {$received_protocol}{spam-scanned}} \
{!eq {$received_protocol}{local}} \
{exists{/home/${lookup{$domain}lsearch{/etc/virtual/domainowners}{$value}}/.spamassassin/user_prefs}} \
} {1}{0}}"
[b]headers_add = "${if !eq {} {${lookup{$local_part}lsearch{/etc/virtual/${domain}/aliases}}} {X-is-alias: yes}{X-is-alias: no}}\n\
${if !eq {} {${lookup{$local_part}lsearch{/etc/virtual/${domain}/passwd}}} {X-is-pop: yes}{X-is-pop: no}}"[/b]
retry_use_local_part
transport = spamcheck
no_verify
2)You'll have to have your user_prefs file add 2 extra lines. To make them globally added, add these lines to your /usr/local/directadmin/data/templates/user_prefs file:
Code:
report_safe_copy_headers X-is-pop
report_safe_copy_headers X-is-alias
or just to your own local /home/username/.spamassassin/user_prefs file for testing with 1 user.
3) Change your filter to use the new data. Your /usr/local/directadmin/data/templates/filter_userspamfolder will have to look like this
Code:
if
$h_X-Spam-Status: contains "Yes,"
then
|*if DOVECOT="yes"|
if "$h_X-is-pop:" is "yes"
then
save |HOME|/imap/$domain/$local_part/Maildir/.INBOX.spam/new/ 660
elif $local_part is "|USERNAME|" or "$h_X-is-alias:" is "no"
then
save |HOME|/Maildir/.INBOX.spam/new/ 660
endif
|*else|
if "$h_X-is-pop:" is "yes"
then
save |HOME|/.spamassassin/user_spam/$local_part@$domain 660
elif $local_part is "|USERNAME|" or "$h_X-is-alias:" is "no"
then
save |HOME|/.spamassassin/spam 660
endif
|*endif|
finish
endif
Of course, to make any template permanent, be sure to copy it to the custom folder first, and work with it from there.
This may not be the final answer to the problem, but will hopefully spur some new ways of trying to deal with it.
And to point out, the drawbacks with this method are that you'll have the 2 extra headers in all of your emails. If anyone knows of an easier way to get the info from the directors in the exim.conf over to the filter without having to use headers, please let me know
