Sending Email using IP Address instead of Domain Name

Question

I am trying to avoid running through DNS servers to get an email message to an address on one of my hosted virtual accounts.

I know I can surround the IP address with sq

Answer 1

A virtual host needs a domain name in order to figure out what to do. You want to send it to an IP address instead of a domain name. Thus it is not going to work through normal methods. You might be able to specify a "default" domain if none match Otherwise, your only hope is to manually forge email. By this, I mean:

telnet 123.456.78.9 25
HELO myhostname.mydomain
MAIL From: 
RCPT To: 
DATA
From: myemail@mydomain
To: user@domain.com
