Emails won't deliver

I keep getting return emails with this in it, saying it could not be sent

553 sorry, that domain isn't in my list of allowed rcpthosts (#5.5.3 - chkuser)

 

Hi Billabong,

Sounds like you need to contact your email provider to confirm both that your email client configuration is correct (even if it used to be) and that everything is OK at their end also.

HTH

Cheers

 

thanks for replying, I forgot to mention that Im using Outlook 2007, does that make any difference?

 

May I play through?

This is probably wrong, but I have had issues like this in the past when sending an email to multiple recipients, when one of the addresses was incorrect/unresolvable. The last time, none of the messages would send. Are you trying to send to multiple people? Maybe one of the addresses is faulty. Or cannot handle some sort of attachment/file too large? Doesn't sound like a NOD32 problem. But, have you tried disabling any outgoing scanners just in case? Just a thought...

 

Hey splnkr, I was sending to one person and it got returned 3 out of the 3 times i tried to send it, so I sent one to someone else to test it and it got returned also, . How do i disable the outgoing scanner, is it the Emon, do i just disable it or something internally, thanks for all the help
