Sending email from CommunityServer

I am receiving the following error from my CommunityServer logs in regards to sending emails:

System.Runtime.InteropServices.COMException (0x8004020F): The server rejected one or more recipient addresses. The server response was: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.5.3 - chkuser)

DiscountASP.NETuses "POP before SMTP" and I'm hoping there's a way I can get around this...any ideas?

 

Thank you, sir. Worked great.

 

Hi Bruce


Thanks for the information.</o>
I changed the pointer to ?localhost? and all worked well.</o>
What threw me completely was that one website worked and one gave an error.</o>
Some information in the knowledgebase regarding this error would have saved me a lot of wasted time.</o>
Thanks again</o>

Hello Bruce
</o>
I am running the same application on two separate DASP accounts.
Both applications are using the same web.config file with only the ?connection? and ?email? names/passwords changed appropriately.
I am receiving the following error message from ?ONE? of my DiscountASP hosted domains. ?rcpthosts #5.5.3 ?chkuser?
</o>
The error occurs during the ?password retrieval? module, but strangely, only on ONE of the applications/accounts.
</o>
I have read the knowledgebase article covering Microsoft Access configuration.(This is not the answer)
</o>
I have tested my applications using the exact same user account (user_name/password/email_address), ONE application sends the retrieved information (as expected), while the other application produces the error.
If both of the applications were producing the error, I would suspect that I had missed something, however, with the error only occurring in one of the applications, I suspect that the DASP accounts have been set-up differently, can you help.
</o>
Thanks
