It can't be on my end, tracert communicates directly with the routers. If it shows it
going from one router to another and then back to the first, that's what the routers
are reporting.
However, it does show the packets going through now (and ping is working). The router
at 209.140.169.85 is now sending packets to 209.141.77.194, which then goes to the
mail server. I can now telnet to your mail server (although it responds with 220
SMTP/cmap ready_________________..., which sounds like a non-IMail mail server; IMail
does respond on the POP3 port though).
If users can connect via POP3/IMAP, but it is slow and times out, it probably isn't a
DNS issue.
I'd also have to rule out the router now, as it seems to be working all right, and
almost certainly wouldn't interfere with POP3/IMAP traffic but not SMTP/web traffic.
That sounds suspiciously like a firewall issue.

I'd checked my DNS Servers, and did a ping and traceroute from an external
unix shell.
I am not getting any TTL expired in transit error, nor am I seeing a loop
anywhere. Could it be on your end?
To Recap:
Our users from Florida cannot access our IMail Server except by using the
Web Interface. POP and IMAP will timeout while trying to download the email.
I'd checked the DNS servers on our end, and pinged as well as tracerouted to
our mail server from an external unix shell, and it's working as expected.
No loops, and no TTL expiration....
What else can be causing this problem?
Also, by the looks of it, our users can send mail with no problem. I see
email from their accounts in the queue all the time.
Thanks
-Pat

Subject: RE: [IMail Forum] Problem downloading mail
Is this mail.novaratech.com you're talking about? First, you should note
that you have 2 MX records for mail.novaratech.com -- if it is one server,
there should only be one MX record (although it won't do any harm to have it
there).
Trying to ping mail.novaratech.com returns a "TTL expired in transit", which
likely means a routing loop. In fact, a "tracert 209.141.79.234" shows it
going from 209.140.169.85 to 209.140.169.81 back to 209.140.169.85. So you
do have a routing problem. Packets are never reaching the IMail server.

ports 21 and 113 has been open. This problem just started happening when we
moved from MS Exchange to IMail.

This is not an Imail pb.
Check with your firewall vendor and docs about how to open the
firewall to permit SMTP and POP3 protocols through.
