I am a registered Spamcop user (I love my spamcop.net address!) and I use it as my primary address, pulling email from assorted lesser-used POP accounts.
I have activated the Mailhost system for my account, and added my ISP's information as well, and it seems to be working well. (I use RCN.com as my cable modem ISP)
However, in an effort to stop abuse of badly configured mail servers on the ISP's network, it has blocked the ports needed to send mail thorugh anything but its own servers. (i.e. I can "POP and IMAP" from Spamcop, Mac.com, RCN.com and everywhere else, but 'SMTP' only through RCN.) This gives every mail I send RCN headers, and causes the mailhost registration to fail as the headers don't match the domain it was sent to.
Is there any way, as yet, to add a domain/ISP without going through the automated reply-to-Spamcop message that is being sent out? ...or am i missing some previous explained point somewhere.
