Hotmail and Yahoo Domains

[David-Ross]

Hey,

We currently have a default standard installtion. i.e. not tweaked it or anything.

When we send emails to hotmail or yahoo it keeps failing. however we can send to other people i.e our selfs and people on our server.

I have checked our spam assain which is not even enabled so what could be the problem mates?

For large email companies, you will need to insure you have reverse DNS working, for that you need to talk to your data center or whomever you got your IP addresses from. You also will need to insure you have spf records for you domains.

What error messages were you receiving?

The following recipient(s) could not be reached:

*****@hotmail.co.uk' on 19/08/2006 00:40
550 "Unknown User"

 

[toml]

That error tells me that the yahoo user doesn't exist.
