Got hit with a zillion incoming connections today,
most of which were empty, had to increase smtpds to
500 to deal, but postgrey barfed much above
250.
Running FC3. Is there an upper limit to smtpd
for postgrey's sake? CAn postgrey be changed?
What is the error (logfile entry)?
Show output of "postconf -n"
Show *all* entries from the logfile for one incident
When default process limit was set to 500, the postgrey we are using
started to fail, causing mail to not be delivered, here are the errors,
zillions of them. We are using David Schweikert's postgrey 1.2.1 with
postfix 2.1.5. Lowering default to 250 allowed things to run.
