2nd newbie question: outgoing reply-to

With yalls help I have postfix working - Thanks! But I need to set ALL outgoing mail to be from a very specific username@domain in order to get the receiving SMTP relay to accept it. I can do this on each message with mail -r username@domain But this means redoing mail commands all over

Another newbie question: I am setting up Postfix to replace a long-standing qmail system. My plan is for all domains to be Virtual Mailbox domains. My question: what do I set mydomain to? I have myhostname set to mx[12].example.com, myorigin to myhostname, and mydestination to myhostname

That works ! Thanks to both of you. It may take the risk to irritate some postfix aficionados, but I find that the postfix documentation is very dense and you need to read it from end to end before getting the big picture. The most discouraging is that few relevant information can be found on

Hi all, I've spent a lot of time trying to configure virtual aliases. Command 'postmap -q "whate...@i.try" /etc/postfix/virtual" always returns the first result after just one aliasing, even if a second alias is matching. Here is an example : # pwd /etc/postfix # cat virtual a...@virtualdom
