[Dovecot] Dovecot not starting

[Antonin Karasek]

Hello everybody,
sorry for stupid qustion, but I have following problem:
I succesfully installed Dovecot on Debian (from source). Now I want to run 
it. I tryed:
# /usr/local/dovecot/sbin/dovecot
#
but nothing happened:
# ps -Af | grep dove
....... ps -Af | grep dove
# 

What is wrong? 

I want Dovecot to serve POP3 over SSL. 

Many thanks and sorry again :o)
