I have a strange problem. Have to Exchg 2003 servers (with MX records at ISP), to which email can be delivered. 2nd one just added recently. It will eventually be made into a Front-End Server.....now both are backend servers.... email comes into the system....our spam filter logs show it coming in and PROCESSED NORMALLY. This means it was not blocked for delivery in anyway to the user inboxes. (Running GFI Mail Essentials For Exchange). Anyway, the email does not get to the user inbox. Some email gets thru, some does not....almost looks like email that came in on the 2nd server is not being delivered. Have a mail archive set up, where a copy of all inbound and outbound email is forwarded to JOURNAL@<domain.name>. This mail archive has no record of the email either. So the emails are disappearing after passing successfully thru the spam filters. (BTW, have forwarded all spam to my inbox, just in case, but nothing). The all email queues are empty on the exchg servers. Need help. Please advise. Thanks.
