Pkg exim4 users - Apr 2008 - Aliases and 'additional addresses in same delivery'

Hi list,

I''ve set up a virtual domain alias router which uses files in a
directory whose names correspond to domains, like so:

  /etc/exim4/virtual/<domain> 

One such file includes this line:

  test : seb at smolny.plus.com, sdt at smolny.plus.com, sebyte at
smolny.plus.com

When an email is received for delivery to test@<domain>,
/var/log/exim4/mainlog reads:

 ... => seb at smolny.plus.com ...
 ... -> sdt at smolny.plus.com ...
 ... -> sebyte at smolny.plus.com ...

The manual (info "(exim4)Log line flags") says that lines which
include ''->'' are ''additional addresses in the same
delivery'' but the
email is only received at the first address listed
(seb at smolny.plus.com) so what does ''additional addresses in the same
delivery'' actually mean?

How can I ensure mail is delivered to all three addresses?

Any help/tips/suggestions much appreciated.

Sebastian

That means that the message was delivered as a single message with
three RCPT addresses in the envelope, which is clear because all three
destinations are in the same domain.

Educate the MX of smolny.plus.com to do a seperate delivery for each
Recipient as it is expected.

Hmm...  interesting.  Can I assume Exim will always slap three addresses
on the same envelope if the recipents all belong to the same domain?

Hmm... very interesting.  So PlusNet''s email servers are at fault.
They''re a pretty big ISP in the UK.  I doubt they''ll change
things just
for me.

Have you ever encountered mail servers that only do local deliveries to
the first address on the evelope before?

That''s exim''s normal mode of operation. It can be massaged to
do
things different.

That can happen, for example, if POP3-Multidrop is in the game. Some
MTAs deliver a message only once if both deliveries would end up in
the same mail store.

Many thanks for the clarification.

Well, you''d be doing a public service if you brought this to their
attention.  I doubt you''re the only one affected, even if
you''re the
only one that noticed.
