Can someone (briefly) tell me about the following SMTP dialog. This
is from memory and may not be exactly right, but I hope you can
recognise it:
TICK 123456789
250 123456789 That's the ticket!!
Is this some way of avoiding the very easy method of spoofing mail by
making your own telnet connection to a sendmail daemon and typing at
it. As you have probably guessed, we have a few jokers that like to
do this and would like to make it harder to do without being found.
