Hi
I am going nuts here. Everytime we try to send a mail, the following is displayed on the console:
10.03.2008 14:41:50 Router: Failed to connect to SMTP host 123.456.789.123 because 221 mail.company.com SMTP Service closing transmission channel
10.03.2008 14:42:08 Router: No messages transferred to 123.456.789.123 (host 123.456.789.123) via SMTP: SMTP Protocol Returned a Permanent Error
10.03.2008 14:42:13 Router: Failed to connect to SMTP host 123.456.789.123 because 221 mail.company.com SMTP Service closing transmission channel
What does the “221” mean? Other servers are able to send mail through 123.456.789.123 (which is in the dmz). I know there have been a change of firewall lately, but the server is able to see the dmz server on 25 and 1352
Please help!
