I think one of the early versions of Exchange 4.0 or perhaps it was
Outlook 97 unpatched had a problem with Bcc recipients.. but Exchange
in and of itself shouldn't.

Yeah - It's odd... It happens with both Exchange Clients and Outlook 98.
It really seems to be a problem with the Exchange Server, but it is version
5.5 with SP2 ??? I'm stumped.

Do you have a firewall or other mail relay server in place?

I would start by enabling Message Arvchival and SMTP protocol log in IMC
props/Diag loggin.
After restart IMC will save copy of each message to \exchsrvr\imcdata\in and
incoming SMTP conversations to files in \exchsrvr\imcdata\log
See how message appears there.

Well, an Exchange server will leave the To: header blank, it doesn't
rewrite the RFC822 header at all. So Id' suspect it's either the
client or the Unix box.

Er.. well, Exchange would never put the undisclosed recipients thing
in a message and I'm not sure about messages in a pickup directory
from Exchange. If you can crank up the logging on the IMS and actually
look at the data being transmitted by the Exchange server... that's
the only way I can suggest determining what's actually doing it. And..
if it's Exchange, I think a call to PSS would be required since I've
never seen that behavior from Exchange before. Sorry.

OK, I'm not too good at interpretting these logs. I turned the protocol log
on and this is what I find? How should it look for Bcc recipients?

Well, to begin, they'd be on the _inbound_ connections. Each thread
has its own log file (that's why there're more than one in the
directory).

In your log (edited to reduce unnecessary clutter), they'd appear as
below:

Didja notice there ISN'T a "Bcc:" header?
.

IOW, either <stephe...@esc.ipex.com.au>,
<stephe...@affa.gov.au>, or <step...@yahoo.com> could be in the
"Bcc:" header of the message when it got to the transmitting SMTP
server. But it'll never be sent.

Either way will work. If all three recipients are in the same domain
then sending three "RCPT TO" command and one copy of the message is
the "approved" way. If the recipients are in separate domains then a
copy must be sent to each.

SMTP isn't that smart.

It isn't Exchange. Exchange does nothing with the message body (which
is where those "To:" headers are located.

Thanks Rich, but how can I tell which server is at fault? Is it the
Exchange server sending it wrong. When I looked at logs on a server that
sends correctly, it actually appeared to break the message up into 3
separate messages, whereas with this one, it had all addresses in the same
message? I'm guessing that when the two servers establish a connection they
work out how they can send information to each other. So how can I tell

which one is moving the Bcc recipients into the 'To...' field of the
message?

Thanks Rich, I'll get hold of the ISP which has control over the UNIX server
and get them to look into it.
