Re: Outside Mail Delivery Stalled -- sudden Problem

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance


- Are the messages making to your SMTP/Exchange server *at all*? Check the
SMTP log?
- If not, does the external sender get a NDR?

Isolate the issue -
- whether it is network connectivity issue
- smtp connectivity from outside the firewall (will have to monitor smtp
connectivity from outside and inside)
- smtp connectivity from inside as well (check smtp service, smtp virtual
server, connection restrictions on smtp virtual server in terms of number of
messages per connection, number of connections, et al)

Dear All,

Exchange 2003 on Windows 2003. Using automatic updates.

Overnight, our exchange server abruptly seems to have virtually stopped
delivering e-mail from outside our local network. A few messages drip
trhough, but very few it seems. If I send 5 test messages from hotmail,
one may get through. I've uninstalled Ninja spam prevention software from
Sunbelt. That doesn't seem to be the issue. I've uninstalled e-Trust
anti-virus software and excange agent from the mail server. That hasn't
helped.

Are there any exploits or viruses going around that could cause this kind
of behavior.
