Hi Everyone. I am trying to gifure out why I am getting a 451 error when clients are trying to send email:
Client error: Task 'mail.csdsinc.com http://mail.csdsinc.com - Sending' reported error (0x800CCC6A) : 'Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: 451 mail server temporarily rejected message (#4.3.0)'
Here is a tail of my smtp log.
@4000000047586d0f1cf5eae4 simscan: connect error 2 @4000000047586d0f1d36b4d4 connect(): Connection refused @4000000047586d0f1d3e6594 qmail-smtpd: qq soft reject (mail server temporarily rejected message (#4.3.0)): MAILFROM:<removed to protect the innocent@@ edgemore.com http://edgemore.com> RCPTTO:removed top protect the innocent@csdsinc.com mailto:innocent@csdsinc.com
Clam & Spam logs are normal.
Any ideas?
Since Qmail isn't a supported package on CentOS, you will get less help than you probably want. But SMEServer is based on CentOS and uses qmail. Maybe they have some clues if you troll their FAQ's or list.
