Do send strings allow variables? e.g. can one do
send "HELO $MACHINEDOTS\r\nQUIT\r\n"
and have it expanded properly?
It could unfortunately be either of those issues. So long as the xymonnet
tester is not performing real send/expect cycles but simply pre-loading
the buffer, there's always the chance of this type of message.
I don't believe the send string is parsed for variables, however you may
be able to get away with hard-coding the current server itself there.

The default test in protocols.cfg is

All of my smtp servers accept the connection, return the 220 response,
and
return a 50X response due to the mal-formed "mail" command. The test
result
in Xymon is green because of the 220 response, but my smtp logs an error
for each connection.
I can replace the send-string with:
send "quit\r\n"
and get better behavior, but I expect that I'll need to make this change
every time I update Xymon. It does not appear that re-defining the smtp
test in a later (included) .cfg file replaces the first definition.
Two questions:
Is there anyone for whom this test is _not_ filling up the error log on
their smtp server?
If I edit the native protocol.cfg, am I correct that I'll need to
replace
protocols.cfg with each code update?
One option here is to place your edits in a separate file included at the
top. But generally, yes. A later one will have no effect.
