[Pkg-nagios-devel] Bug#525976: Bug#525307: check_smtp: invalid option -- n

[Thomas Guyot-Sionnest]

Regarding the recv() failed, why don't you use check_tcp instead?
check_smtp isn't meant to monitor a broken SMTP server and report it as
OK; if it doesn't work anymore it may be because an actual bug was
fixed.

check_tcp will return OK is it manages to connects - you can also add
options to send and/or check for received data. See "check_tcp --help"
for more details.
