Validate your DNS settings with regards to anti-spam techniques (DKIM, SPF, SenderID, Domain Keys).

There are some DNS tricks floating around there that mail servers use to calculate validity for your sent emails. DKIM, SPF, SenderID, Domain Keys and they are all used by different mail servers in their own way. The DNS setup can be a bit not too obvious so testing for it is great.

Well, just email these two addresses (/verification services) and they will answer with a report on those validation techniques mentioned.,

Also! When adding those TXT or SPF records in DNS make sure the "value" (or "result" or whatever) like "v=DKIM1; k=rsa; p=a9c....85ee" are entered with enclosing quotation marks (").
