But the problem is that my ISP, OptOnline, blocks port 25 both incoming and outgoing so I am forced to use their SMTP server to get mail to the outside world (I use a 'reflector' service from no-ip.com to get around the incoming mail issue, I point my MX record to thier machine which in turns passes the mail to my system on an alternate port).
I assume that the problem is that b-dub.org is associated with an IP address which is in a dynamic block? As my ISP provided mail '[EMAIL PROTECTED]' which I send/recieve via outlook on a winXP box does not get scored this way (well at least my friends with Hotmail and yahoo accounts do not report that messages from said account go into their spam folder)?
I should think that the headers would be much the same as in both situations the mail originates from 24.44.185.239 and goes directly to the SMTP server mail.optonline.net and out to its destination?
Thanks for all the assistance, JP
dyndns.org allows the use of non-standard ports for mail relay
I'd be interested to see a message sent from your outlook client and one from the 'problem' machine in order to compare the headers. Feel free to directly send me one sample from each and I'll post the results.
