bounced emails - postfix related question

[sygram]

Greetings to all,

i have installed centos 5 and the latest ispconfig 2.2.23

I am using my machine to send emails from various different applications. When the email goes out to aol, the email is bounced back. I have setup a reverse dns record for my domains and added the "abuse" email accounts.

The problem i think is that on the undelivered report that i get i see "This is the mail system at host myserver.privatedns.com." I think instead of saying "at host mydomain.com" it uses the localhost name thus getting bounced back.

What do i have to do to send properly this message ? If i login to the local smtp from my application and then send the emails will this fix the problem ?

If i just change myhostname parameter to a "proper" domain would this be considered as spoofing ?

Thank you very much

Your answers are appreciated.

Best Regards,

Leon

Please change myorigin to your desired hostname in /etc/postfix/main.cf.
Also, do you have SPF records for your domains?
Please check if your server is blacklisted: http://mxtoolbox.com/blacklists.aspx

Thank you for your reply Falko. I appreciate it.

This is what i thought as well. The only thing that i need to check is if i send the emails from domain2 account ie sales@domain2.com and i have set domain1 at myorigin parameter, is this going to be ok ? or treated as spam ?

Thanks

That's no problem, but make sure you have an SPF record for domain2.
