I have a (hopefully Simple) question regarding the config of a qmail
server a college and myself setup resently.
I have a qmail server hidden behind a Firewall from both my internal
network (users) and the external network (internet).
Now we have noticed since changing over that there is a 30 second delay
on any email transaction from either the internal network or the
external network.......and we could not figure out why.......
Tonight I was thinking that the Firewall could be the problem when a
Firewall Techie told me that he has seen this problem before and
suggested that it is the mail server doing a reverse-IDENT and the
Firewall is blocking it (both internally and externally) and the default
timeout is about 30 SECONDS........sounds like to solution.
But is this the case with qmail?
I answered this question myself by allowing my Firewall to pass the
ident port for the internal network and now email is delivered instantly
to my internal users......but the problem still exists for my external
users and mail servers that are trying to send me mail or receive email
from my protected server.
And how do I stop it or change the timeout to be 1 second if possible?
I hope someone can help me with this problem.
Thankyou for your time,
Dean Oliffe
