I was using the queviewer and noticed a lot of spam so I suspended the messages in there then rebooted. Upon restart the above error was generated. I checked the network adapter for and is set for the server. I tried a reboot again and still the same error. Please help!

Now in the quiwviewer only "submission" is listed. Should there be more items there besides spam domains?

451 You have exceeded your messaging limits
 
The program cannot send more messages, because your mail account / mail server has a limitation.
Please contact your mail administrator or mail provider regarding this issue.

Please note, that the program cannot send out more messages as your mail server allows. Some mail server have limits, e.g. some allow to send only x messages per hour. You can use the List Settings -> Outgoing Mail Server (SMTP) -> Limit feature to adjust the program to any limit.

If you have setup a limit in the List Settings -> Outgoing Mail Server (SMTP) then the task (mailing) will stop, the task will be re-scheduled and will continue automatically after the specified delay

if you suspected the spam mail, then we need to look for spam mail source and blocked it. Since you view it using queue viewer, double click on one of spam mail to get more details of the mail
