I am a newer! I want to implement a function when a new mail is coming to dovecot , I can execute my custom program,something like insert mail to database!
I find a notify plugin in dovecot.
How can I use it? I have makefile the sourcecode of the dovecot, and compile it and also see the code of mail-log , notify!
Is there any document about how to dovelop a new plugin, or is there any other easy way?
thanks!
