We had the same problems with our Pop-before-SMTP users, sending emails directly to MTA, where DOS_OUTLOOK_TO_MX always fired. What we did: - first, we lowered the score of DOS_OUTLOOK_TO_MX, to prevent such cases - we wrote a plugin to dynamically assign trusted_networks on the fly with getting the information stored in SQL for pop-before-smtp users - after that we have raised the score of DOS_OUTLOOK_TO_MX :) You can read more about troubles with dynamic users and solution to it: - http://wiki.apache.org/spamassassin/DynablockIssues - http://wiki.apache.org/spamassassin/POPAuthPlugin regards, -- Jernej Porenta <jernej.pore...@arnes.si> ARNES, Tehnološki park 18, p.p. 7, SI-1001 Ljubljana, Slovenia tel: +386 1 479 8800, fax: +386 1 479 88 99 ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
