Bruce,
What do folks suggest for the largest maximum size of the left-hand
field of a message-id (id-left)?
BL> As RFC 2821/2822 are relatively recent and are proposed standards
BL> (vs. 821/822 which are full standards), for maximum interoperability
BL> I'd stick with the appropriate limit from 821/822 and related standards.
BL> There, a msg-id has angle bracketed local-part(_at_)domain syntax and the
BL> maximum length of the local-part is 64 octets (RFC 821 section 4.5.3).
An interesting data point. I understand you viewing one left-hand-sade
as being the same as any other. However RFC821 has nothing to do with the
Message-ID field.
BL> Note also that the maximum length of the domain part is 64 octets per
yes, constraints on the right-hand side are pretty well established.
that's why i only asked about the left-hand side.
