Bug#309639: exim4: Code 450 Errors

[Gordon Haverland]

Package: exim4
Version: 4.50-6
Severity: wishlist


One of the guys in my LUG is in the anti-spam business.  He was testing
out some new stuff, and wanted some of us (with different MTAs) to send
messages to his machine.  Exim4 seems to fail in a bad manner in this
test, hence the report.

His intention is to only allow a single recipient per connection, and
the test involved having 3 addresses in the To: field.  The message sent
back to Exim (from his logs is):
 450 Only One Recipient Per Connection - See
   http://www.XXXXXXXXXXX.net/policy.html

The first address is delivered to by exim, the other 2 addresses in the
To: field are ignored.  Exim never does attempt to reconnect and send
the second and third messages, per the error message from the
destination site.  Exim does not warn the user that copies of 2 of the 3
recipients is never sent.

I am by no means an expert with exim.  The only changes to the
configuration from what is in the package by default, are what debconf
can do.
