Hi Aaron,
Yes, please open the ticket on JAMES.
I suppose you mean 'empty' MAIL FROM, and not 'null'.
In other words, in case of MAIL FROM command not issued, do we have to
throw and exception, and if yes, which one?
(sorry, no time atm to dig into the RFC)
Thx, Eric

appropriate, JAMES or PROTOCOL? I'll essentially just include this thread,
including Stefano's responses -- I can't add much beyond his statement that
RFC1123 5.2.9 says it's a must and that setting a null MAIL FROM is a common
technique for preventing bounce loops.
Thanks,
Aaron

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?)
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
logs:

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
