[Dovecot] DSpam mysql-plugin (was DSpam plugin)

[Michael Blinn]

After wrestling with Johannes's original plugin, I had a go at the mysql 
plugin that Tim wrote, as described here:
http://members.plug.org.au/~linuxalien/dokuwiki/projects:dovecot-mysql-dspam-plugin

I kept getting "Error: imap dump-capability process killed with signal 
11" when attempting to start dovecot with this plugin. I traced the 
error to line 656 of master-settings.c in the dovecot source, in the 
'get_imap_capability' function. In this function, it notes:
"Reloading configuration. Don't try to execute the imap process again. 
Too risky and the wait() call below will break it anyway. Just use the 
previous capability list we already had generated."

I changed the source so that the function always ran
"    set->imap_generated_capability =
                        p_strdup(settings_pool, generated_capability);
                return TRUE;"

instead of going through the function where it had on the wait described 
in the comments.

Now, voila. Dovecot starts without complaint, the plugin works, the 
delivery and moving of email works.

I'm assuming I've screwed something up by skipping the rest of this 
get_imap_capability function. My C skills are a few years rusty. What 
are the ramifications of skipping the remainder of this function?

Thanks,
 Michael
