[kwlug-disc] Strange gmail issue

[Chris Frey]

Hi list,

For the last couple weeks, any email that I send from my cdfrey at foursquare.net
address to other people's gmail accounts gets flagged as spam.

With recent testing, I've found that I can change my From line to
various other valid email addresses of mine, using the same system
to send the mail, and Google doesn't consider me spam.

Somehow, just my exact address seems to be seen as spam.  Not my domain.

How do I track this down?  Does Google have ways to contact them about this?
