I have a client running SBS 2003 who has recently relocated offices. Low and
behold the telco didn't connect the ADSL line on time so we are using dialup
until they fix that up.

The problem is that the ISP blocks port 25 on dialup so we have to set the
smarthost setting. That is all fine and the exchange serve can actually talk
to it (see further ahead) but all emails just get stuck in the queue. Lookin
g
at the logs it seems that there is a handshake between the two servers but
the connection either terminates or hangs after "DATA". The log looks
something like this (doing this from memory at home as the dialup connection
s
is way too slow for surfing)

ehlo domain.com
250
MAIL FROM:me@domain.com
250
MAIL TO:you@anotherdomain.com     ---> A bit weird as I was expecting RCPT
TO instead
250
DATA
250 - OK go ahead
CONNECTION TERMINATED


Any ideas?

BTW I can setup an outlook express account on any computer and use that
smarthost as the smtp server and send emails no problem. So it is definetely
related to exchange/virtual smtp server.

Server is 2003 rel 2 with all the updates (Running WSUS)

A network trace is probably the better way to see this. Have you tried?

The ISP is likely terminating the connection, but to see it you'll want that
trace.  You could just call the telco and ask them what they expect in this
situation.  Might be faster that way.

I'll try that. Will be a while as I have to make my way there and dig out
the acct info they want before they talk to me. The acct was setup before my
time so i have to get other ppl to help me find the info.
