How to set up a PTR-record on shared hosting account? (to avoid my emails going into "Spam")

[gunwitch]

I have a website hosted on one of HH's shared servers. Now I'm planning to start using PHPList (mailing script) for sending newsletters to registered users.

So I started reading about that and found that correctly set PTR record is important for proper delivery of my e-mails (avoiding spam filters).

Currently my PTR-record is:

222.246.43.208.in-addr.arpa	IN	PTR	208.43.246.222-static.reverse.arandomserver.com

Can I make it more "personal" (e.g. include my domain name) if I'm on shared server?

On a shared server all mail is sent from the same IP so we cannot modify the PTR record for that IP. The only way to have the PTR records for an IP you're sending mail from would be to purchase a VPS.

Thanks, Brian. This is what I actually thought, but decided to make sure and ask here.

So, if I can't set PTR-record, what else I can do to protect my newsletters from going into 'Spam'?

Should I add the SPF-record (TXT), which allows 208.43.246.222-static.reverse.arandomserver.com to send emails on behalf of my domain?

Login to cPanel and go to the 'Email Authentication' section -- from here you can configure DomainKeys and SPF records for your domains, this will assist in verifying the authenticity of any email sent from your domain

Thanks!

I have added SPF record manually (wasn't that hard) and enabled DomainKeys in cPanel.

Although the DomainKeys section displays a strange warning, emails sent by phpList, are shown as DK signed in Gmail and Yahoo
