These look like the bounce address in the MAIL FROM, so it's a
reverse-path as defined in RFC 5321 section 4.1.2 which is the same as
RFC 2821 section 4.1.2 other than formatting.

If you follow through the BNF, the * is in the local-part of the mailbox,
which is an Atom which consists of a string of atext, which is indeed imported
from RFC 5322 which says in section 3.2.3 that "*" can appear in an atext.

On the other hand, it also says that the maximum length of a
local-part is 64 characters.  Depending on the username and domain
Mike's seeing, the local-part may well be longer than that.  I have
seen actual mail systems that choke on overlong local-parts, although
there's little reason for them to do so.

RFC5322 and predecessors. Either dot-atom or quoted-string are permitted
for the local part of the address. Characters allowed in dot-atom are
listed in 3.2.3; many other characters including whitespace are allowed in
quoted-string.

That would be a good clue that they're likely to be doing other things
wrong too.

You can always use this handy-dandy regular expression to validate email

For the record, we aren't speaking about 'Friendly Names', but the 
userpart of the addr-spec address


But a pointer to an RFC where it is permitted, that I don't find..

(And yes, Thanks Al it has been used in the wild as you pointed out for

It's more a 'gotcha' that post delivery processing systems may not

But the page you linked to clearly says that the asterisk is allowed in

Return-path headers using VERP in this way, with asterisks in the
username part like this, can be traced all the way back to LISTSERV in
the 1990s.  It's a long standing practice. If you block based on this,
you'll block a few spammers or commercial mailers who used or use
LISTSERV, or who rolled their own mailing list software in a way where
they copied the VERP styling exactly, but you'll also probably block
lots of academia and random non-spammy discussion lists.

When I worked for Digital River approximately 150 years ago, we had an
internal platform that had its own databases and UI for list
management and campaign configuration, and then when you hit "send" an
email template was built that was then handed off to the LISTSERV
server which then did all the building of the messages. The
Return-Path header for these messages was always of the format
owner-nolist-x-y*username**domain*-suffix@sender.

[mailop] Mailing List Address Formats..

2019-01-11 Thread Michael Peddemors

owner-nolist-cp_enews-190110p-gqfjbpue*username**domain*-suf...@digital.annexbusinessmedia.com

(Where 'username', 'domain','suffix' are placeholders)

I don't know of this particular mailer, but can I get some feedback to 
confirm that the '*' character is not a permitted character in an email 
address? (user name portion)


Or has there been a change to RFC's that I am not aware of?

Grepping of logs, only shows a couple cases of it.. but wanted feedback 
on this, as some as you can see are important legitimate senders..
