my emails are going to spam folders
I'm on a VPS. I realized that (unfortunately after months) emails sent from my server are going to spam folders.
it seems I need to use a resolvable hostname. what does this mean?
what should I use?

Your hostname probably does not match a domain name; run the command hostname to find out. It should give you something ending in your domain; if this vps is sending email from example.com, your hostname should be either example.com or somethinghere.example.com.
If this is not so, you can change your hostname using either your provider's control panel or hostname yourdomain.com .
Also, it would probably be a good idea to set an SPF record for your domain; the simplest way in your case would be to put a TXT record in yourdomain.com with v=spf1 a ~all .

Also check and make sure that your PTR matches your mailserver's FQDN, as that's a fairly common antispam check, and something a lot of people don't have set correctly.

spf is not there but reverse lookup is
why it shouldn't be able to do a reverse lookup
dig domain.com MX
:mx.domain.com
dig mx.domain.com
:192.168.1.1
dig -x 192.168.1.1

Sigh.
A fairly common problem with sending mail (or the inability to successfully do so) is a mismatch between what the server reports as its FQDN during SMTP, i.e.
Code:EHLO foo.bar.com
Code:dig -x 300.400.500.601 node666.supercalifragilisticexpealidocioushosting.biz
Also, the sending server's PTR and FQDN don't need to be the same as the domain's MX record, unless people are being lazy or incompetent with their SPF records, but that's a whole different issue. In fact, there are some substantial benefits to having the MX record be something completely different... but that's neither here nor there.redpin.com - offering amazingly competent email, dns, and web hosting since 2002... because someone has to!

Alright, whatever, you win. I defer to your clear, indisputable, irrefutable, well-documented, and eloquent arguments. I would like to take this opportunity to publicly thank you for schooling me on the hidden mysteries of email and this DNS thing which I know nothing about; you are my master and I am but an unworthy pupil.
Also, I would like to take this opportunity to publicly apologize for somewhat nastily thinking you had no bloody clue what you were on about and were simply post-whoring; clearly that was a rash judgment for which I assure you I now stand suitably chastised.
To reiterate: intodns.com can solve all the worlds ills, the PTR of a server must in fact according to the RFC you so kindly linked to be identical to the MX record of each and every domain for which the server handles mail, and I'm a complete n00b who is unworthy to open my cakehole and spread unfounded and baseless opinions about those things (i.e. everything technical) with which I am hopelessly inept.

I am sorry it posted twice, and no i didn't link any rfc
intodns does not solve all the problems but help to determine some of them
and yes PTR should be identical to MX record of the domain but multiple domains can have the same MX record I am not talking about domain A record hereEuropean Xen based VPS Hosting

Hello,
Following should be set in order to prevent mails from going to spam folder :-
1. RDNS for the server should be setup.
2. SPF record should be set for each account.
3. DomainKeys should be setup for each account.
4. Check whether the DNS configurations are correct on the server.

Add SRV and TXT record to your hostname form the DNS zone. It will resolve the issue.

Make sure that your IP is not blacklisted in any RBL List. Try to check in mxtoolbox.com database.
