Dictionary attach
« on: December 09, 2005, 12:17:35 PM »
Email sent to my account have been bouncing back to the sender with the following message:
Your message cannot be delivered to the following recipients:
 
  Reason: Remote SMTP server has rejected address
  Diagnostic code: smtp;550 Connection denied after dictionary attack

Any ideas about this problem?

The sender server is most likly being disallowed because someone on the sending server tried to use a dictionary attack on your server to send spam to someone on your server. Contact support about it at support@lunarpages.com. Be sure to include the full bounced message including the headers of the bounced message.

Hi~

We've been receiving bounced back emails showing  550 Connection denied after dictionary attack as well, coming from 2 different SMTP servers. Seems to start happening at around beginning of this week...

Thanks~
