Hi Aaron,
Sorry to return you the question, but what does SMTP RFC
(http://www.ietf.org/rfc/rfc2821.txt) tells about empty mails? (is it
allowed?)
I was supposing that, but didn't take time to point the exact line in
the RFC.
We'd better throw a NonCompliantRfcException than a AddressException,
especially when it is thrown by the MailAddress constructor.
WDYT?
Eric
"MAIL FORM:<>" is REQUIRED to work. This is the way DSN bounce are delivered.
Mailservers not supporting this "sender" are listed by
http://www.rfc-ignorant.org/
Stefano
In any case, it would be better to a more specific and throw an exception
with a correct readable message.
Based on your finding, it will be good to open a JIRA on
https://issues.apache.org/jira/browse/JAMES or
https://issues.apache.org/jira/browse/PROTOCOLS (it will depend how/where we
will fix it).
Thx, Eric

On James Server 3.0 beta 4, we are seeing lots of these errors in the

So I tried to reproduce it and while I can't be 100% sure this is what is
causing it, it does at least reproduce it:

Is there a setting that will allow us to process emails with an empty MAIL
FROM, or is this just a bug that needs to be submitted somewhere?
Thoughts?
Aaron
