James said, "for Box A to have mailmain utilize Box A's postfix, in the main.cf file for postfix, you will need to enable relay ability for the IP 10.0.0.1 and 127.0.0.1"
Thanks for the help! Just the push in the right direction I needed. For archives' sake, I'll cc the gentoo-user list with the answer to my problem. Pretty simple really. Apparently postfix, by default, will only delivery mail to local users (because the default setting of local_recipient_maps says so). I simply opened /etc/postfix/main.cf and added the following line to the bottom: local_recipient_maps = Yes, there is no setting after the equals sign. Setting it to nothing tells postfix not to try to map recipients to local users, and once it stops doing that, I stop getting an error 550 everytime it tries to relay a message. Thanks for all the help! I have another minor question regarding Fetchmail and Mailman, but if I can't figure it out, I'll post to a different thread so as to keep threads clean. -Tom Caudron -- [EMAIL PROTECTED] mailing list
