mail setup recommendation

[Roger Grosswiler]

my setup is similar.

i entered in /etc/main.cf the following for virtual-support:
virtual_maps = hash:/etc/postfix/virtual

make sure, alias_maps is like this in the same file:
alias_maps =

...in this case, you don't need to support /etc/postfix/aliases, you have
to insert your users in /etc/postfix/virtual instead.

so, a user in /etc/postfix/virtual looks like:

mydomain.net                        anything
roger at mydomain.net                  roger

have a look at the first line: gwch.net ist my domainname, i tell there
postfix to accept anything for this domain
the second line is my mailbox (which should usually be a unix-user,
related to shadow-accounts, but i use mysql for authentication)

if you have a further domain, e.g test just add:

test.net                        anything
email at test.net                  mailbox-username

now, you can put anything you want for the e-mail-adress, but a user in
unix has to be present.

now, make sure, that the dns-entries of those domains have the appropriate
mx-record to your mailserver.

btw. don't forget to '/usr/sbin/postmap virtual' to create the virtual db.

is it what you where looking for?
