Greetings all, I'm seeing a good amount of MSExchange Transport Warnings and some Errors in the Application log. This is from a SBS 2003 Server with Exchange 2003.
Here are 2 examples of warnings, the recipient in this case is someone that my clients email:
This is an SMTP protocol warning log for virtual server ID 1, connection #36. The remote host "217.x.x.x", responded to the SMTP command "rcpt" with "450 4.7.1 <user@domain.com>: Recipient address rejected: Greylisted for 5 minutes ". The full command sent was "RCPT TO:<user@domain.com> ". This may cause the connection to fail.
This is an SMTP protocol warning log for virtual server ID 1, connection #17. The remote host "205.x.x.x", responded to the SMTP command "rcpt" with "451 Internal resource temporarily unavailable - ". The full command sent was "RCPT TO:<user@domain.com> ". This may cause the connection to fail.
Here are 3 examples of the Errors:
This is an SMTP protocol log for virtual server ID 1, connection #19. The client at "59.95.152.151" sent a "helo" command, and the SMTP server responded with "501 5.5.4 Invalid Address ". The full command sent was "helo static.jaipur.bb.59.95.152.151/25.bsnl.in". This will probably cause the connection to fail.
This is an SMTP protocol log for virtual server ID 1, connection #7. The client at "190.237.5.224" sent a "ehlo" command, and the SMTP server responded with "501 5.5.4 Invalid Address ". The full command sent was "ehlo JOSÉ-PC". This will probably cause the connection to fail.
This is an SMTP protocol log for virtual server ID 1, connection #1. The client at "123.240.232.206" sent a "helo" command, and the SMTP server responded with "501 5.5.4 Invalid Address ". The full command sent was "helo ØpØp-PC.tbcnet.net.tw". This will probably cause the connection to fail.
The errors to me read that someone is sending whatever command to the Exchange server and it is giving them the appropriate response. The warnings though I'm not sure about.
Any help is greatly appreciated.
