I have about 6 qmail servers up and running in different parts of
California. For the most part life has been pretty easy with them. I have 3
machines giving me a headache currently and was hoping for some help. (I
know 50% is a failing number)
#1) A local machine running RH Linux and qmail 1.03. It had been running
great for the last 9 months. I recently had an IP change on the machine as I
switched DSL providers. I made sure all of the control files got changed and
the new tcp rules added. However, it appears to not want to pop mail with
out a long delay. My windows clients need to keep hitting wait. It
eventually works, but it is very frustrating, considering it worked fine
before the IP change. My guess is it relates to DNS. Am I on the right
track, or has anyone else seen this? Is there a way I can fix it without
long phone calls to my provider educating them on DNS and stuff :)
#2) Is rather similar. Was built in house (RH Linux and qmail 1.03)and then
sent out. Worked fine here, however in the clients location they get
constant timeouts on SMTP and need to keep hitting wait as well. I am using
the -R in the tcpserver startup so that it won't try to resolve the local
IPs, but it is still happening.
#3) Similar still. A large mail server I just built using Matt's BSD-qmail
toaster setup. In house worked fantastic. Bring it in the field for a small
ISP, and even trying to do a localhost port 25 connection is taking
sometimes 10 minutes!?!
All of these problems seem related and it is probably something really
simple that is driving me crazy. If anyone has input on what I'm doing wrong
I'd really appreciate it.
