Re: Delayed emails

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Well John, we're frighteningly in sync. I did just that, bypass the Symantec
AV, and things seem to be working appropriately. The funny thing is,
everything within the Symantec product was showing it was functioning
properly, but when I tried to telnet in to port 25, or did other tests from
outside, connections were being refused. Once I bypassed it, telnet
connections were successful and mail flowed. Thanks for your help with this!
When I read your last two posts, I had just finished doing what you
suggested, which was nice confirmation of my troubleshooting process.
Thanks again!

Yes, bypass your Symantec AV filter gateway for a test to see if mail starts
flowing properly. I have not worked with Symantec AV Gateway filter but I
would imagine there should be some sort of monitoring or log that you can
enable to insure its passing the mail properly.

I just did a ping right before your reply came in, to the website of client
who was reporting that their emails weren't getting through this morning.
The
results were normal. No lost packets, some high times, but nothing
glaring. I
have Syamantec AV for SMTP gateways sitting in front of my Exchange
server,
getting the incoming mail and scanning for spam and virus content. It's
worked normally up until now, but when I was just doing an email server
test
from websitepulse.com, I was getting an error saying no SMTP server
available. I checked and the service is running, but it's 3 year old
software, so maybe that's the suspect. What do you think? Is there some
way
to analyze why the SMTP connection is not being made?

I would lean towards your WAN circuit having some issues at this point,
possibly CRC errors. Have them perform a circuit test to insure its
operating correctly. As for LAN software, I like Ethereal and its free.
You can also perform a simple continuous PING test with Ping -t command
to
see if it times out after so long to an external IP or address.

John,

Thanks again for your reply.
I ended up finding out about the ExBPA and ran it against my Exchange
200
server and came up with a couple fairly minor things.
The thing is, nothing has changed substantially interms of hardware or
software or configuration which could account for this.
I also ran the MS SMTP analyzer and everything came back normal, though
that
was for outgoing.
I have been using an outside mail monitoring service for the last
several
days, and notice a continual timing out of the test messages, or
slowness
in
the time of response. So I'm guessing it's periodic WAN or LAN
congestion.
Would network monitor be the best bet for checking out the LAN? Or can
you
suggest some other tool? I was going to have my bandwidth provider
monitor
my
link to get some data on the WAN side. I haven't had any complaints
about
IE
timeouts, though sometimes it is slow, but we have 125 people on a 5MB
link,
so it's not going to be blazing.
It's the intermittent character that is so frustrating to diagnose.
Plus
that it's incoming.
Any further suggestions would be greatly appreciated.

What version of Exchange Server are you running? ExBPA is Exchange

Practice Analyzer, please download and run it against your Exchange

As for test your network equipment, most new equipment now a days is
managed
so you should be able to login to your Router or Switch to turn on
some
logging to see if you are getting any errors. Are you noticing any
intermittent timeouts with your Internet connection when browsing with
IE
or
downloading a file?

John,

Thanks for the reply. What is ExPBA? How would I test my WAN
connection?
Router or Firewall or switch?

I am having an intermittent problem with emails being delayed for
anywhere
from 20-30 minutes to 5 hours. There is no consistency interms of
sender
or
receiver. It seems to happen incoming and outgoing, though I hear
about
it
mostly incoming from outside clients. When I originally
investigated
this,
I
saw that I was deficient in RAM, and increased it so that the
Commit
Charge
peak was well under the RAM amount. I had had no problems prior
to
this.
Everything had been functioning smoothly for 2 years.
It seems totally random. One user told me that he recieved
response
to
a
group email from an outside client hours before the original
email
was
delivered! Emails to/from particular clients will go through
normally,
then
one will be delayed for 30 minutes up to hours.
I'm at a loss as to what to do.
I thought maybe it was a DNS issue, but that seems in order. The
processor
seems to staying below the 50% level for the most part. The Peak
Commit
Charge is at 1.7GB and I have 3 GB in the system. Maybe it's
network
related,
but I'm not sure how to find this out.I'm not sure how to go
about
diagnosing
this in general. Any help will be greatly appreciated
