Question

I would love to configure my postfix/virtualmin setup so that when I create an email account test@test.com, it would also catch all the mails sent to test+spam@test.com. Gmail offers this functionality, though, I wouldn't have a clue how to do this.

What I've done already is Googled it, http://www.virtualmin.com/node/27709 is what I've stumbled upon. Though, unable to understand 'the answer', I thought maybe someone here could help me out.

Was it helpful?

Solution

Postfix and virtualmin both support alias "like" gmail with simple config. Just go to "System Information > Postfix Mail Server > General Options" (http(s)://<yourserver>:<vitualminport>/postfix/general.cgi). Search for "Separator usernames / address extensions" field (press ctl+f and type "address extensions", for quick search) and fill it with "+".

Alternatively you can edit /etc/main.cf and place a line like

recipient_delimiter = +
