How to tell which mail servers greylist

[calin79]

Hi - I've been having problems receiving mail, and I noticed on the boards that one of the suggest solutions was to make sure I'm not using a forwarding address that graylists (greylists?) spamgourmet. Unfortunately, I'm really not sure how to do that... of course, I sort of doubt it's a greylisted server, as I'm using gmail (no, you nasty spambots, not the same username as on here... hah!), and I'm sure that if they were one of the ones greylisting you, there'd be a lot of posts about it. But still... for future reference it would be good to know how I would find this information out.

Perhaps you guys could post a list somewhere of the mail servers that blacklist you?

Thanks!
