dovecot - Mar 2008 - How LDA deliver mail

hi,all
 
 
    I read some part of the source code for studying and interesting. But i face
trouble when I read the 'deliver.c'.
    In file 'deliver.c' on line 812 , there is a function named
'deliver_mail', see below:
    deliver_mail(storage, mail, destination, mailbox)
 
    I couldn't find out where is this function defined and how it was
linked.
 
    Thank u for your help.

the function is defined by plugins. look at dovecot-sieve source code 
for example.
