smtp;553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)

Does that mean that my hosting is blocking overclockers emails? Seems to have just started since you changed your website over. Looking at my Web hosts FAQ (UK-cheapest) it says the return email may have a link to forward the email to to get it unblocked?

the envelope sender is mandrillapp.com, and the only thing that changed when we changed our server is our dkim and spf became valid

We don't send from our own servers, so the envelope is different to the from - really no serious mail service should take any serious notice of that, especially considering the valid dkim and spf!

Just as a curiousity, I sent a subscribe email to one of these mail tester sites:

http://www.mail-tester.com/web-pGR4dX

It only really tells you it's not blacklisted, dkim+spf are valid and it scores well on a standard spam assassin rule set - but all sorts of spam rules are configured on all sort of servers, gateways, anti-virus and even mail clients! I've personally always found google and outlook do a good job of stopping nearly all spam with very rare false positives.

Might be worth looking at DMARC as well. Also have a read of:
