I found the main.cf here is the seciton of it that I think you are talking about.
myhostname = hans.dnsdojo.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
#mydestination = hans.dnsdojo.com, localhost.dnsdojo.com, , localhost
mynetworks = 127.0.0.0/8
mailbox_command = procmail -a "$EXTENSION"
What should i change? should i change relayhost to mailhost? How do I find out what I need to put in there? I have att dsl. my e-mail is firstname.lastname@example.org
Thanks for the help,
