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 - 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> RCPTTO:removed top protect the innocent@csdsinc.com
Clam & Spam logs are normal.
Any ideas?
Thanks,
Ed
