I found (I'm learning how e-mail works) a
.forward file in a user home folder; emails should be forwarded to mailboxes of other users. Email addresses are written in
user+folder addressing notation, but instead of a
+ sign I found
- sign; if I would like forward a spam message to Spam folder of a
user I would write
user+Spam@domain.com, but I found
user-Spam@domain.com. The file contains email addresses in form:
This is an email server using Postfix.
firstname.lastname@example.org` email@example.com userNfirstname.lastname@example.org
Is there any difference?
