Yes, we support sub-addressing, VERP style.
Subaddressing allows you to use multiple email addresses as subaddresses within a single e-mail account. Our system supports subaddresses with minus addressing. It works by adding a “-” sign followed by a keyword to the local part of the email address, just before the “@” symbol.
For example, if your email address is firstname.lastname@example.org, you can use subaddresses like email@example.com or firstname.lastname@example.org. Messages sent to a subaddress will be delivered to the main address (email@example.com in this case). You can use subaddresses for different purposes such as filtering emails, tracking the source of spam, or organizing messages into specific folders.
You can see our FAQ on this here: Email subaddressing.
Note that we only support the “-” character for sub-addressing and CiviCRM by default uses the “+” character. The truth is, however, that VERP separator may be any other character as well. It is configured via the “Administer -> CiviMail -> Mail Settings -> VERP Separator” area in CiviCRM.
