swift vs phpmailer

I have a mail server sending email verification to registering users with PHPmailer. No bulk mails, no newsletters, no mailing lists. Anyway Hotmail (live and msn) decided to drop all mails coming from my domain. They are not even sent to Junk folder, they are just dropped without any notice. I am not blacklisted, I have spf records, I have a nice rDNS.

So I tried swift mailer. Guess what? They are correctly delivered. Delivered to the Junk folder, but at least delivered. I don't know why, the differences in the headers generated by the two libraries are minimal (Message-ID, X-Mailer and X-LibVersion I'd say).

Anyway If you are blocked by hotmail and you are using phpmailer, give swift a spin.

Version 4 should have an even higher success rate. It doesn't break any of the implemented RFCs anywhere to my knowledge, whereas v3 (and every other PHP mailing software I know of) loosely follows the RFCs, but not to the word.
