Hi folks,


I have 6 dumUs (guests) runnig on Xen. Their hostnames are;

dum0 - xen0.satimis.com (host)
dumU1 - xen1.satimis.com
dumU2 - xen2.satimis.com
dumU3 - xen3.satimis.com IP - 192.168.0.113
etc.


xen3.satimis.com is a mail server. It can send mails but unable receive mails because Internet can't find its address. Port 25 has been forwarded to its IP already. Is there any way solving the problem instead of renaming its hostname as satimis.com? Please advise. TIA

Your MX record needs to point to the ip/hostname that is external. Once a message hits that, your port forwarding comes into play.

Hi ph34r,


Thanks for your advice.


Did you mean MX record on Register's site? Please explain in more detail. TIA

Your mx record (if you have one) in DNS needs to point to your external IP and/or an externally reachable hostname. Once it hits your IP, the NAT forwarding will send it to your internal addressed mail machine

If you don't have an MX record set up, then whatever IP satimis.com is at will get your mail, and then it can forward it inside to your internal vm

Hi ph34r,


Thanks for your advice.


I have the MX record on Registrar's website pointing to "xen3.satimis.com" and "xen3" pointing to "external/fixed IP'. Now the mail server can receive mails as well. But mails sent to this server must be addressed to "user@xen3.satimis.com". Without the prefix "xen3" the mail will be rejected.


Is there any way getting rid of "xen3"? Where shall I look at? TIA

What rejects the mail? Your box must be configured to accept mail for both xen3.satimis.com and satimis.com, and the MX record for the satimis.com domain should point to xen3.satimis.com

"satimis.com" is missing on "mydestination".


Now problem solved. Mail sent to satimis@satimis.com can be received by the server.


Thanks
