Idea Harness commented on JAMES-1422:
-------------------------------------

This is very important to us to be fixed ASAP as we are using Apache James 3.0-beta4 as an
MTA for MS Exchange 2007 whose NDRs (non-delivery reports) or bounce messages have an empty
MAIL FROM email address and hence Apache James 3.0-beta4 gets the javax.mail.internet.AddressException
mentioned in this bug.

> It does allow you to enter it, then a RCPT TO and DATA, but after you finish the DATA
command it throws an exception:

> This is a pretty important issue as its required by RFC1123 5.2.9 to allow empty MAIL
FROM due to bounce emails often using empty MAIL FROM to prevent bounce loops.
> As Stefano Bagnara pointed out:
> "This is all best summed up by section 5.2.9 of RFC1123, which says:
> ----
> The syntax shown in RFC-821 for the MAIL FROM: command omits the case of an empty path:
"MAIL FROM:<>" (see RFC-821 Page 15). An empty reverse path MUST be supported.
> ----
> So, an empty email address is NOT a valid email address, but an empty email address is
valid in an 
> SMTP conversation as a way to say "no mail address".
> IIRC James 2.3 dealt with this using null sender in case a <> was received (so
to not build an "invalid" empty address object)."
