Script doesn't create /etc/postfix/virtual while /etc/postfix/master.cf has a reference to it

[NecRaul]

As mentioned in the title, when running the script on a clean install with nginx configured, the script doesn't create virtual but it uses hash:/etc/postfix/virtual for submission (in line 132) -o smtpd_sender_login_maps=hash:/etc/postfix/virtual. This results in a Relay access denied in some cases.

This can easily be fixed with using the same thing main.cf uses for smtpd_sender_login_maps which is pcre:/etc/postfix/login_maps.pcre. The script automatically generate the /etc/postfix/login_maps_pcre file in line 115.
