I have a problem with Outlook 20000
If I receive a message from someone who has asked for a confirmation of
receipt and I then click on OK, the confirmation is not sent and a message
says that it rejected me as the sender. Response 501, syntax error in
argument. However if I type a reply and send it on the same account, all is
OK.

I am sure I am overlooking something simple,but can't think what! The SMTP
address is definitely correct.

Any help much appreciated.

From what system does the respose come, yours or the sender's? Post the
complete error text (but masking any real mail addresses).

The resonse appears to come from mine.

The message could not be sent because it rejected you as the sender. Server
Response: 501 Syntax error in arguments'. (Account: 'xxxxxx', SMTP
Server: 'mail.btinternet.com', Error number: 0x800ccc78).

Where xxxxxx is my email address. As I said before, I can send emails in
the normal way on this account so it is only if I respond to a request for
confirmation.

Geoff.

It's probably because the RR is returned without a valid From field and in
an effort to stop spam, the server is rejecting mail that does not have a
valid From field. If you aren't authenticating with the outgoing server, it
might help (because it accepts all mail from validated senders), otherwise I
don't think you'll be able to return RR.

FWIW, RR are often dropped as spam for this reason.

So, you are using BT Internet, correct? The message is from the BT Internet
server. If this were to happen to me, I'd be on the phone to BT Internet.
