Whenever an email is sent via ActionMailer, and the recipient is using
Outlook 2003 (with SP2 installed), the e-mail is getting put in the junk
e-mail folder. Since Outlook doesn’t give a reason it was tagged as
junk, it’s hard to determine what to change.
I’ve compared the message headers of the “junk” mail and a valid email
sent through Outlook, and the headers are nearly identical. (I’ve even
tried tweaking the ActionMailer e-mail so that it is 100% identical, but
it still didn’t work).
The only thing I can possibly imagine is, since it’s a multipart (html
and plain text) message, that Outlook doesn’t like the way ActionMailer
splits up the MIME Parts??
Has anyone run into this before? I’m trying to create a marketing system
through our rails application, and the last thing I need is for all of
our Outlook recipients to not even see the e-mails.
