dovecot - Jul 2013 - avoid log message when using nagios check

Hello,
I'm using a nagios check to monitor dovecot status, since dovecot v2 I
see those syslog messages on every nagios check:

pop3-login: Aborted login (no auth attempts in 0 secs)
imap-login: Aborted login (no auth attempts in 0 secs)

I tried to avoid those messages sending a logout string:

check_imap -H localhost -e 'OK' -s 'a logout'
check_pop -H localhost -e 'OK' -s 'quit'

but now I get

imap-login: Disconnected (no auth attempts in 0 secs)
pop3-login: Disconnected (no auth attempts in 0 secs)

what can I do to avoid a log message on every nagios check?

thanks!
Llu?s

Hi Lluis!
Maybe just filter it in your syslog?

Just do a complete login/logout sequence.
I have developed some perl scripts to do so.

This is fine for the nagios checks, but we are facing similar
problems with our loadbalancer, which is just doing TCP Healthchecks
on the IMAP/POP3/SIEVE ports, so being able to disable the warning
for trusted networks would be really helpful.
