Like we use recipient_delimiter in Post-fix such that if email address is "abc@host.com" then if we set "recipient_delimiter" to "+" (plus sign) in the /etc/post fix/main.cf file, now even if someone send an email on "abc+foo@host.com" or "abc+bar@host.com" then it will be delivered to the mailbox of "abc@host.com" only that is the plus sign and the content after the plus sign is ignored.
My problem is I want to achieve same in Q MAIL, can someone suggest me how to achieve that.
