SendMail Configuration Problems

bselzler · 06-11-2001, 11:31 PM

Hello Team,

I'm not actually sure if I'm having a configuration problem or if the problems are just because I'm a newbie.

Basically I can send mail out from my system, RedHat 7.1, just fine. I use the user name of bselzler, and my host name is ns.sezonline.com/www.sezonline.com.

When I send mail to someone it uses the return address of bselzler@ns.sezonline.com. However when someone tries to reply to the message the mailer return's the following error;

"All relevent MX records point to non-existant hosts"

I have an mx record pointing to ns.sezonline.com (I've also tried sezonline.com) in my sezonline.com bind file. Additionally I have a CNAME entry for mail. Do I need some other record somewhere? Do I need an A record for mail?

I'm kind of stuck at this point so any info would be helpful. Thanks.

A\Is your DNS working properly and is your CNAME record duplicationg or trampling another name record? (Check logs when you start/restart/reload named)

Can they send mail to you@yourdomain.com?

Did your mailer select the default reply-to or your sendmail (as the MTA)

I believe its working correctly. http://www.sezonline.com is working. And I don't see any errors in the system log.

>Can they send mail to you@yourdomain.com?

No. Thats the problem. I can send mail out, but no one can send mail in.

>Did your mailer select the default reply-to or your >sendmail (as the MTA)

When people try to reply it used bselzler@ns.sezonline.com, which is what is used when I send mail via the command prompt from my system.

Thanks for the help.

And the above error is quite correct! A lookup for your MX returns this:

Code:

sezonline.com.sezonline.com

which isn't valid!!!

So I recon that your records are infact not correct... It looks like your MX record points to sezonline.com and you haven't put a traling . so BIND has appended sezoneline.com to the end of it. Point it to ns.sezoneline.com. and all should be fine! (assuming sendmail is setup correctly)
