Hi,
I have exchange 2003, enabled for using as pop account to my client, i can receuve emails while i am at home(out of LAN), but when i send to any e-mail account i ge the following msg:
'whatever@hotmail.com' on 5/5/2005 11:13 AM
550 5.7.1 Unable to relay for whatever@hotmail.com,
I can telnet to the exchang server from out on port 25.
I can reveive e-mail from anywhere.
I cant send e-mails unless i am connected to the LAN.
DNS is resolving from nslookup with no issue from outside and inside.
Pop service is enabled.
I have a Macfee websheild, I have already by passed it, still no used.
My FW is allowing all the protocols to flow in without any restriction, I still cant get it sone.

How have you configured the relay settings on the SMTP Virtual Server?
Are you authenticating SMTP when you send email?

this'd probably be a good time to note that allowing everything at hotmail.com to relay through your servers is a really bad idea unless you want your server blacklisted. Just a thought but do you have multiple "from" addresses at home and is one of these a hotmail account?
If so that might be what's causing you grief - try checking the "from" field before sending..

As I stated above:
In order for you to be able to relay mail for the domain @hotmail.com, through your work server, you would have to allow that domain, authenticated user, specific user, IP Address or computer to relay that email address through your server.
that domain, authenticated user, specific user, IP Address or computer being the key point. If he is using hi swork exchange server as his smtp, and if he is wanting to make it from his hotmail account, he would need to let it relay, preferribly authticating by his user account through his server. I was just stating SOMETHING would have to be open to let it relay through.
