I'm having a LOT of trouble with something I thought was going to be pretty simple... We have 2 domains here: dconx.com (our primary domain) and subscribercentral.com (old domain kept mainly for the e-mail addresses) Most users here have e-mail addresses in both domains in their AD e-mail list. I'm trying to get E2K SP2 to accept mail from the subscribercentral.com domain and deliver it to the right person. I've tried adding a second SMTP site, SMTP connectors, the works and all I get is "550 5.7.1 Unable to relay for user@xxxxxxxxxxxxxxxxxxxxx" Right now the only way I can get this to work is with an SMTP connector that accepts subscribercentral.com mail and pushes it to dconx.com. This is a mail loop but the messages get delivered... Anything else I try just returns relay errors. :o( _Any_ enlightenment here would be most appreciated.
