Re: The length of a email address

[Luis Rodriguez <luisro58@xxxxxxxxx>]

Pat,

RFC 5322 gives a max value of 254 characters. The corresponding wikipedia
entry shows:

The format of email addresses is local-part@domain where the local-part may
be up to 64 characters long and the domain
name<http://en.wikipedia.org/wiki/Domain_name>may have a maximum of
253 characters - but the maximum 256 characters
length of a forward or reverse path restricts the entire email address to
be no more than 254
characters.[1]<http://en.wikipedia.org/wiki/Email_address#cite_note-0>-
formally defined in RFC
5322 <http://tools.ietf.org/html/rfc5322> (sections 3.2.3 and 3.4.1) and by RFC
5321 <http://tools.ietf.org/html/rfc5321>.


HTH,
