Question about bangs (exclamation marks) in local-parts of addresses: My
reading of the expansion of local-part to dot-atom to atext is that a bang
is (1) permitted in the local-part of the address and (2) may appear
_anywhere_ in the local-part.
Specifically, constructions such as <!bob(_at_)domain(_dot_)com> and
<bob!(_at_)domain(_dot_)com> are permitted, even though they technically
violate
parsing rules for bang addresses.
Correct?
The bang is legal in the left-hand side (mailbox) of an Internet email
address. From the perspective of Internet standards, the mailbox string is
uninterpreted.
From the standpoint of an MTA's implementation, precedence between bang at
at-sign depend upon the needs of the organization that is running the
MTA. There are times when either precedence makes sense.
Such considerations are entirely outside the purview of the IETF.
Well, there *is* RFC 976.
