[ Classic Linux and DirectAdmin. ]

If incoming mail is received by our servers such that a + (plus) or - (hyphen-minus) character is found anywhere to the left of the @ character, then the incoming message will be delivered to the email address formed by considering only the part to the left of that character.

On our old servers this feature was called hyphenated suffixes, because only the hyphen-minus was supported. This feature is generally called plus addressing because most service providers, if they support this feature at all, require a plus.

We support both hyphen-minus and plus.

This feature lets you quickly make up a new email address at any time, by simply adding a plus or hyphen-minus and some additional characters into your email address.

(If you use more than one plus-addressing character in an email address, the leftmost character is the one that counts.)

Please test the correct functioning of this feature before you begin to widely deploy it.
