which version of qmail is installed?

[Heiko Romahn]

Hello,
how can I find out which version of qmail is installed? I have to maintenance 
a mailserver on which qmail is installed. But I'm realy confused, because the 
manpages show me version 1.01 and the owner of the server told me that's a 
qmamil version 1.03

Thanks in advance,

Heiko
