My Exchange Server (Installed on SBS 2003) has become extremely clogged up due to a continually occurring error:
Event Type: Warning
Event Source: MSExchangeTransport
Event Category: SMTP Protocol
Event ID: 7002
Time: 9:19:07 AM
This is an SMTP protocol warning log for virtual server ID 1, connection #4503. The remote host "184.108.40.206", responded to the SMTP command "rcpt" with "451 Requested action aborted: local error in processing ". The full command sent was "RCPT TO:<###########@gmail.com> ". This may cause the connection to fail.
This error seems to occur at least 3 times per minute. I've tried changing the network card, resetting DNS, Exchange, SMTP, POP3, Active Directory, the server itself and the stores. I'm able to telnet to the server, perform an NSlookup and do all of the basic Network troubleshooting stuff (Ping, TelnNEt, NSLookup, TraceRt, ect). The reverse-DNS lookups are setup correctly. This issue has been plaguing it for some time now, and we need a solution. Any help or suggestions anyone can provide would be helpful.
Emails are going out, but slowly. At this very moment I have 355 emails to one address in the Queue. In a perhaps related issue, we have a mail-enabled Public Folder, which is rejecting MOST, but not all incoming emails.
