While you're looking into a way to drop these connections as quickly as possible I would turn down the number of SMTPD processes on your server. That should give your server a break. I'd start at 50 and tune from there.
change your master.cf to something like: # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== smtp inet n - n - 50 smtpd On Wed, May 26, 2010 at 1:42 PM, Matt Hayes <domin...@slackadelic.com> wrote: > On 5/26/2010 3:35 PM, brian wrote: >> On 10-05-26 03:31 PM, Matt Hayes wrote: >>> >>> I wonder if using something like postscreen from the 2.8-snapshots would >>> help to curtail some of the resource usage. >>> >> >> Thanks, I'll check it out.
