I use external DNS through my ISP And run my mail server behind firewall with NAT
In this case I setup the A and MX records as if the mail server Actually using the Public IP address 54.234.232.12 nat to 10.0.0.20 (example ip addresses) I have setup in T4SERVER.INI MAILSERVER=10.0.0.20 MAILPORT=25 In my mail action I just use an valid email account as defined by my mail server. Then I use the HOST file an create a poor mans DNS for internal use 10.0.0.22 mydomain.com Ben Johansen - http://www.pcforge.com Authorized Witango Reseller http://www.pcforge.com/WitangoGoodies.htm Latest downloads & List Archives @ http://www.witango.ws -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Lee Sobo Sent: Friday, June 14, 2002 4:40 AM To: Multiple recipients of list witango-talk Subject: RE: Witango-Talk: SMTP Load In regard to mail issues, we have plenty. It seems that we have alot of problems sending mail also. What I have setup is a second mail server that is behind my firewall to send out mail only to avoid the smtp relay hassle. When I send out mail, it has a from address of [EMAIL PROTECTED] The ip address of the server sending the mail is not in my dns, but I have a real mail server that is. Also, the non-real mail server is behind the firewall and is using nat. My question is, will the ip address of the non-real mail server be switched by the nat device like regular ip traffic is? And if that is the case, what do I add to my a records and mx records? >>> [EMAIL PROTECTED] 06/13/02 10:34AM >>> John, Your server should be able to handle that many messages in under 5 minutes. Some mail servers do reverse DNS lookups and other verification to verify your mail servers identity. Make sure you have everything in your DSN for that mail server just as if it were a mail server receiving mail. Make sure your domain has an MX record, make sure yourdomain.com has an A record, and the ip address on your server has a reverse dns entry. When my reverse dns entries were not set up correctly, I had trouble sending e-mail to AOL.
