[CentOS] Turn off fetchmail warning?

Is there any way of turning off the fetchmail warning
----------------------------------
fetchmail: Warning: the connection is insecure, continuing anyways. 
(Better use --sslcertck!)
----------------------------------
which I get when fetching imap mail from my college department?

I know they should get a root certificate,
but I'm told they are looking into it,
but that could take forever.

I know I could just filter out the warnings in .fetchmailrc .

But I'm wondering if there is any option in fetchmail to turn them off?
I don't see any in the man page.
