I sent a message and received it back after two days with a permanent error. I was curious why a message with a permanent error sat on the mail box for so long. So I enabled smtpclientdebug on server’s notes.ini and resent the message.
The router is receiving a 550 response:
15/05/2008 11.01.20 [0248:0005-10D4] SMTPClient: ReceiveResponse: 550-111.222.333.444 blocked by ldap:ou=rblmx,dc=bellsouth,dc=net
15/05/2008 11.01.20 [0248:0005-10D4] SMTPClient: ReceiveResponse: 550 Blocked for abuse. See Currently.com - AT&T Yahoo Email, News, Sports & More for information.
Then I asked the router to show me the queue (te router sh queue) and got this:
Msgs State Via Destination
1 Retry( 2) SMTP BELLSOUTH.NET (Push)
Last error: SMTP Protocol Returned a Permanent Error
Next retry: 15/05/2008 11.51.28
Now the router realized this was a permanent error, so why retry?
