rpchosts error

[John Collins]

Hi,
I am getting thie message when I try and send out mail.

553 sorry, that domain isn't in my list of allowed
rcpthosts (#5.7.1)

Can anyone advise me on how to sort it out?

Thanks

John

Whose SMTP server are you using to send outbound mail through? Check with
your ISP to make sure you're using the right server, and that if you need to
use SMTP authentication to send mail, that you've configured it correctly.

Hi again,

Thanks for that. My inbound and outbound mail servers are
configured currectly.
My isp is eircom.net and in & out mail servers are
mail1.eircom.net

Any other ideas??

Are you getting that when you send to *any* recipient? If so, it's something
to do with your SMTP server...perhaps it's blacklisted. Check with the
recipients' admin folks if you can find them.
