The new box has no GUI. The OS is Debian 6.
$ uname -r
The MUA is:
$ mailx -V
The MTA is postfix. (For some reason I can't run "postconf -d | grep
mail_version" so I'll have to ask the sysadmin later about that. But at the
moment, I don't know the postfix version.)
Given that info, which settings changes should I make to proceed with the
testing plan you described above?
So far all I did was:
1. create a ~/.mailrc file with contents:
2. edit /etc/postfix/main.cf and change mydestination to the line below:
mydestination = localhost, localhost.localdomain
I did not restart postfix yet... I appreciate any feedback regarding next
