ActiveSync and Spam

[Guest mkriedel]

I recently switched from a Treo 650 with ChatterEmail and my own mail server to a T-Mobile Dash. I signed up for an exchange hosting deal so I can use the Direct Push/ActiveSync setup.

That all works fine. However, when I send mail from my Dash, it almost always gets marked as spam with the following flags (using SpamAssassin):

spam, SpamAssassin (score=5.663, required 4, BAYES_20 -0.74, MSGID_DOLLARS 1.72, RATWARE_MS_HASH 1.91, RATWARE_OUTLOOK_NONAME 2.78)

Anyone else seeing this/have a fix? It doesn't happen if I send through the built-in SMTP, only through ActiveSync/Exchange. Also, it doesn't happen when I send straight from the OWA that the provider offers, so it must be the Dash.

Any input would be appreciated.

Thanks,

Matt
