Email Address Tagging or SubAddress as default

  • Hi everybody.


    I'd like the feature of gmail to use tagged email addresses (add a tag with + to the mailadress):


    name+[email protected], name+[email protected] oder name+[email protected] etc.


    It is great to filter the mails, to block unwanted or to identify where the spammer get the mailadress from.


    In my IMSCP server it works also with 2 (maybe 1) change and my question is, why not make this as default.
    AFAIK there is no bad side on this change.


    master.conf:
    dovecot unix - n n - - pipeflags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} -a ${recipient}


    Rewrite -d ${user}@${nexthop} -a ${recipient} to -d ${recipient}


    And this line to the main.conf: (maybe this is the default? Not shure)


    recipient_delimiter = +
