Scotts reply yesterday:
<In that case, Symantec *must* return a 5xx response.
Scotts reply today:
<But to a computer, if you look at Appendix E of
<RFC821, it says "The sender should return to the beginning of

<sequence."
Strange, if you look at RFC821 4.3 page 37 "Command-Reply Sequences":
CONNECTION ESTABLISHMENT
S: 220
F: 421
HELO
S: 250
E: 500, 501, 504, 421
MAIL
S: 250
F: 552, 451, 452
E: 500, 501, 421
....
....
....
That means that Symantec Firewall only can reply 421 to Imail if there is a
error before HELO.
Correct??
