Studying dovecot source code (searching for mail_deliver_hook_set)

[chaouche yacine]

Hello dovecot,

I would like to study how dovecot manages quota, especially how it deals with the maildirsize file if one chooses to implement quota according to the maildir++ specification.

I made a number of assumptions :

1. mail is (always/sometimes) delivered with the dovecot-lda binary, which source code is in src/lda.
2. mail is sent with the mail_deliver function which is called from src/lda/main.c and is defined in src/lib-lda/mail-deliver.c
3. mail_deliver function calls the deliver_mail function (it seems to be pointer to a function)

4. according to src/lib-lda/mail-deliver.h, deliver_mail is set with the mail_deliver_hook_set function. Here's what the comment says

/* Sets the deliver_mail hook and returns the previous hook,
which the new_hook should call if it's non-NULL. */
deliver_mail_func_t *mail_deliver_hook_set(deliver_mail_func_t *new_hook);



The problem at this point is that I can't find where is this function called. A grep on the sources only reveals two results :

./lib-lda/mail-deliver.c:428:deliver_mail_func_t *mail_deliver_hook_set(deliver_mail_func_t *new_hook)
./lib-lda/mail-deliver.h:103:deliver_mail_func_t *mail_deliver_hook_set(deliver_mail_func_t *new_hook);

Grep finished (matches found) at Tue Mar 28 17:01:50

According to the changelog this function has been introduced back in 2010. I don't know if it's really used ?



* I am working on the 2.2.13 sources because that's what's installed on my server.
* I couldn't find a developers mailling listed in http://www.dovecot.org/mailinglists.html so I'm just posting this here.
