Site does not accept '+' in email addresses
Posted: 02 Nov 2006, 12:06
GMail allows you to use + signs when giving out your email address to easily identify where mail is coming from, helping to discover where spam arrives from, allowing you to tag mail, etcetera. It works like this:
The following addresses are equivalent:
[email protected]
[email protected]
[email protected]

On a different forum where I raised the issue, someone was kind enough to quote the SMTP specification 2.3.10 to support the argument:
Kind of surprised a mail delivery system doesn't completely abide by those rules - it'd have to be a bug if you're processing email addresses incorrectly.

On a different forum where I raised the issue, someone was kind enough to quote the SMTP specification 2.3.10 to support the argument:
Originally found by BritonguyAs used in this specification, an "address" is a character string
that identifies a user to whom mail will be sent or a location into
which mail will be deposited. The term "mailbox" refers to that
depository. The two terms are typically used interchangeably unless
the distinction between the location in which mail is placed (the
mailbox) and a reference to it (the address) is important. An
address normally consists of user and domain specifications. The
standard mailbox naming convention is defined to be "local-
part@domain": contemporary usage permits a much broader set of
applications than simple "user names". Consequently, and due to a
long history of problems when intermediate hosts have attempted to
optimize transport by modifying them, the local-part MUST be
interpreted and assigned semantics only by the host specified in the
domain part of the address.
