We have a NW4.11 Server runnng GW5.2 POA,MTA,ADA & GWIA. Up until the last 2 weeks everything has been fine but now we are having intermittent problems with internet email. About 75% of mail (incoming & outgoing) is delivered ok but the remainder can take between 1-4 hours to be delivered. There seems no pattern to this: it does not matter who they are from or who they are sent to. It does not seem to matter if there is an attachment or not and it does not seem to matter what time of day they are sent.
At first I thought it was a problem with our ISP but they say there is nothing wrong at their end (but then they would say that) and say that the problem is with our mail server rejecting mail when it’s busy.
I’m not sure what to try next, I am considering downloading an eval copy of NetPro’s MailCentral to see if this can pinpoint where the problem is. Does anyone have any experience with this product? If so, any tips/advice is welcome.
Any other ideas or things to check??
