Quick one here. Id like everyone's input on guranteeing delivery of email. I have an Exchange 2010 server, typical setup.
It seems like my email somehow winds up in the junk mail on occasion at the receiver end.
I did set a SPF record and a PTR (reverse DNS record), and there are only 2 or 3 active email accounts on my server, and they are not sending junk, so I would assume my SCL rating is perfect, so how can it wind up in a junk folder? The only thing i can think of is my signature includes a jpg scan of my signature which is an attachment in some systems.
But if Im missing some things, please comment.
