[Wlug] email sending problem with comcast

HI all, This is driving me nuts...I still have that problem where I get intermittent failures while sending email, even after hard coding the IP number for smtp.comcast.net (they normally have 4 different IPs...I hard coded one to make debug easier). Does anybody know the SMTP protocol sufficiently that they could help me debug this problem ? I have ethereal traces - one when it works, and another when it doesn't. I see differences, but I don't know why, nor do I know what I should do as a remedy. Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org
