Message:
I just pushed a fix to ftpserver.pl that now makes test 1406 run fine even
with your patch applied!

Message:
Yes, the respons should be 250 as defined in RFC 5321 (and also common mail
servers like Postfix and Sendmail send 250 code).

I will check the test tomorrow...

Message:
Thanks for the report and the patch.

First, an EHLO gets a 230 by the ftpserver.pl test server, which seems like
a flaw. It should be 250. Right?

Your patch makes test 1406 break since it assumes a SIZE but the test
server doesn't signal support for it the way you've just added detection
for. Can you check and see if you can make 1406 work, and possibly add a
test that runs without SIZE?

Message:
Problem: SMTP client always sends SIZE (rfc1870) parameter in MAIL FROM
command. If server does not support this param, it can say: "504 Command
parameter not implemented" and reject the message (or send 555 –
rfc1869).

Solution: So we should send SIZE param only if server advertises its
support by "250-SIZE" in response to EHLO. This is done by attached patch.
