SMTP question

I've got a program that sends student grades to parents. I've had a
report of a user running into problem with Groupwise 7, and could use a
little advice.

Here's the sequence I'm using. I've removed email addresses, since they
don't belong to me, but they looked correct.

1. EHLO.
2. auth LOGIN
(Ultimately generates a 235 Authentication successful.)
3. Mail From:
4. RCPT TO:
5. DATA
6. .
(I get a 250 Ok here.)
7. Mail From:
(And things derail here with a 500 Syntax error.)

I don't understand this 500 Syntax error, and the software doesn't
expect it. So the software then issues a RSET, which also generates a
500 Syntax error. Next it tries a QUIT, which also generates a 500
Syntax error. In the end, the software drops the connection and declares
defeat. From what I understand, the first email does indeed go out.

Am I missing something from the sequence? Is there a better place for me
to ask?

Re: SMTP question

This is a MIME GnuPG-signed message. If you see this text, it means that
your E-mail or Usenet software does not support MIME signed messages.
The Internet standard for MIME PGP messages, RFC 2015, was published in 1996.
To open this message correctly you will need to install E-mail or Usenet
software that supports modern Internet standards.

A likely bug in Groupwise. The stupid thing probably was never tested with
the client sending multiple messages on the same connection.

You might want to try a RSET immediately after the DATA comes back, and
before the next mail from:. It might work.
