Not exactly like your situation but I'm in the same boat with some emails being marked spam...
We have 2 options. Educate yourself on how to configure your mail server. In addition to tracking down what may be the cause of this flagging. >> and how to fix it.
Or ask the people who sold you the goods to help with your config.
If you're doing it yourself I would suggest that you.
A) understand (search for) what types of things will make your email get marked.
B) Take a look at your email headers & make sure they're formatted correctly. Best way to do that is to send yourself an email from your localhostserver to a hotmail account or something.
C) go to dnsstuff.com and get a dns report from their service and print a copy of it.
D) Fix all the items that report as (warn) in the report.
E) send an email to the person you know is having the mail marked as spam again (to verify)
F) Ask that person to whitelist you.
G) I may have missed a detail or two in this list but I'll post it as I remember them... (I'm still learning too..)
The only thing "I" have left on my todo list, which is obviously a biggie since just this morning I got a reply from a client where my message to him last night was marked as spam... Is publish my "SPF" record. (which I'm still looking for "exactly" how and where to do that) I know what it is and I've done the SPF wiz / created the txt file... but haven't installed it yet.
Hope any of this helps...
