Hi,

when sending email over cyrus imap, it gives full information about
version. So, an attacker has just to telnet at port 25 to see if his
bunch of exploits fits to it.

That is a dangerous and I would like to suppress all version
information, even that it is cyrus answering, if possible.

Can you do that by just configuring it somehow, or does it need a patch?
