Hi all,
We are testing a new outsourced anti-spam service (Edgewave/RedCondor).
We are letting their systems check for valid recipients using the VRFY
command, but their default verifier uses <someth...@mydomain.com>,
instead of <someth...@redcondor.net> as the FROM address when verifying.
Because I employ anti-spoofing (anything from/to one of our addresses
must be sent through our server or we reject it), we had to set up a
custom verifier in the Edgewave control panel.
Everything is working, mail is flowing, but grepping on
(lost|warning|error|fatal|panic), I see a lot of these:
2013-07-31T10:48:39-04:00 myhost postfix-25/smtpd[17729]: lost
connection after VRFY from smtp446.redcondor.net[208.80.204.46]
with occasional
2013-07-31T10:46:28-04:00 myhost postfix-25/smtpd[17993]: too many
errors after VRFY from smtp644.redcondor.net[208.80.206.44]
tossed in.
Is this normal? Or is this indicative of a problem that should be fixed?
Thanks
