A neglegible one. Yes, I have set up a content filter (amavisd-new).

OK. I have applied configuration updating during a congested moment.. I fear that this has increased congestion as result. Then I have rolled back modifications and all (slowly) have returned to work normally. Finally, I have applied again configuration modification (which uses 'sender_bcc_maps') yesterday night and tomorrow all works fine without (at least at the moment) active queue congestion. What it could be happen? Thanks, rocsca
