[Dovecot] How to write plugin

[Eugene Prokopiev]

I tried to use http://www.dovecot.org/patches/copy_plugin.c as simple
example. My code is attached. I see plugin loading in logs:

Nov 20 12:29:33 mail dovecot-auth: pam_tcb(dovecot:auth):
Authentication passed for enp from (uid=0)
Nov 20 12:29:33 mail dovecot: imap-login: Login: user=<enp>,
method=PLAIN, rip=192.168.46.23, lip=10.0.101.103
Nov 20 12:29:33 mail dovecot: IMAP(enp): copy plugin init
Nov 20 12:29:33 mail dovecot: IMAP(enp):

But I can't see nothing while message is copied :(

I tried to send mail to Fabio M. Catunda <catunda at
contactnet.com.br> yesterday, but I see no relpy. Fábio, can you show
me you code?
