Hello,
Since some days the number of SMTP connections rejected by my server is
increased (maybe doubled). It doesn't worry me. But there is a side
effect because even the number of false negative is increased.
For example, at the moment a spam message with this header is considered
clean by Amavisd-new-2.5.3+SpamaAssiassin-3.2.4:

I use a PRE-LISTING :
reject_rbl_client zen.spamhaus.org
reject_rbl_client list.dsbl.org
And I update SA ruleset regularly with rules_du_jour and sa-update.
How I have to do to make my system more reliable?
Thanks in advance,
rocsca
