userful patch -- finally!

[Alexis Yushin <alexis@NL.net>]

Greetings,

	When Matti was here we found a very annoying bug that would
make smtp client spin if remote smtp server would violate SMTP protocol
by issueing 220 and 551 consequentally without delay and then immediately
handup. Here is the fix. Regards,
								alexis

PS From /usr/include/sysexits.h, exactly the case :-)

**      EX_UNAVAILABLE -- A service is unavailable.  This can occur
**              if a support program or file does not exist.  This
**              can also be used as a catchall message when something
**              you wanted to do doesn't work, but you don't know
**              why.

	One might want to use EX_PROTOCOL instead, but these last
lines from EX_UNAVAILABLE sound just sweet!
