How do E-Mail Aliases Work?

Hey guys,

I was just wondering, How do email aliases work? Where can I edit the file that stores all of these aliases. The reason I'm asking is so that for the roundcube mail login i'd like to be able to login myself as user instead of [email protected] or domain.com_user

Thanks

 

I put a new one below where it says make manual entries below, but no luck. Do I need to restart anything?

 

Whenever you modify /etc/postfix/virtusertable, you must run

Code:

postmap /etc/postfix/virtusertable

and restart Postfix.

 

=/ No luck.

I did:

Code:

sudo postmap /etc/postfix/virtusertable

and then:

Code:

sudo /etc/init.d/postfix restart

and in the /etc/postfix/virtusertable I put:

Code:

bswinnerton    mysite.com_bswinnerton

What did I do wrong?

 

The format of /etc/postfix/virtusertable is

Code:

email_address username

e.g.

Code:

[email protected] username

 

So does that mean that I cannot have

bswinnerton mydomain.com_bswinnerton

?

 

Yes, that's right.

 

=/ Alright thanks!
