The follwing issue showed up around 1 week ago... until then everything was working fine.
Simply put, my exchange 2003 server isnt either receiving or processing email in a timely fashion. I have people who are sending emails to valid emails on the exchange server and they are processed almost immediately. At other times the same senders’ emails are not received into the exchange email box for 30 minutes to 4 hours after the email was sent.
I’ve looked at the logs, changed the hardware (DSL modem w/ static IP's) looked at the error reports, ensured my DNS and RDNS is correct - telneted into SMTP on the server a million times- everything checks out. The only thing that DOES NOT make sense is the inconsistency (sp) of when/how the emails are received. Therefore, I unfortunately do not have the consistency of a single point of error and/or I am looking at the wrong place for a solution.
ANY help with this will be much appreciated. I’m not new to SMTP or Exchange, but just can’t get my head out of the forest so to speak.
If you can help, please let me know what information you may need to assist me with this.
Thanks in advance.
