np, you give me free software, i give you free testing ;)

i have some more so i'll just create tix and send them along

i just switched to using thunderbird and any new messages i send to the 
list are being flagged as spam.  i have no problems with evolution.  
anyone have an idea?

(i can reply using thunderbird, but not send new message)
