adding a PTR record to your DNS?

Hi,
To day I got some e-mail back from some german free mail provider:


While searching the web it seems that this one provider is the only mail provider (freenet.de) doing this check for incoming mail.

I remember me something about AOL is doing the same.

what do you say? adding this PTR record or not? (adding a record for maybe one of thousand e-mails)

this mail was send via some web application

Never used that before. What is it about?

Oh I see. You need to have a reverse DNS entry, otherwise many mail servers will reject your mail or even put you in black lists....

It's about a domain on some shared hosting account...

In that case you should use their mail server. They must have a standards compliant mail server for their clients.
