dovecot - Nov 2008 - More info from mail_log plugin

HiWe need to track exactly when our users read messages. Unfortunately, I
haven't been able to figure out how we can achieve this with Dovecot. Then I
saw the mail_log plugin.Is it possible to extend the plugin to also log system
flag changes? This would be great, because then we could see in the log files
when the Seen flag has been set. Changes in user defined flags would also be
interesting to track.I know this would create a lot of log entries, but for us
this wouldn't be a problem. Maybe the plugin would default to not tracking
flag changes, but could be configured to do so.RegardsBardur Ha Skor

I added this code to v1.2 now. There you can use:

mail_log_events = delete undelete flag_change
mail_log_fields = uid box msgid flags

And it logs like:

imap(tss): Info: flag_change: uid=125823, flags=(\Answered foo), msgid=<foo
at bar.org>

Thanks a lot :-) it works just like I had hoped for with IMAP. Unfortunatly, the
mail_log plugin won't start with Pop3 anymore. I get the following error in
the log:

Dec 18 18:24:49 bardur-desktop dovecot: POP3(bardur):
dlopen(/usr/local/lib/dovecot/pop3/lib20_mail_log_plugin.so) failed:
/usr/local/lib/dovecot/pop3/lib20_mail_log_plugin.so: undefined symbol:
imap_write_flags
Dec 18 18:24:49 bardur-desktop dovecot: Fatal: POP3(bardur): Couldn't load
required plugins

As I mentioned, I want to track when users read messages by looking at when the
\Recent or \Seen flags change. A Pop3 session can set these flags, but I
don't think (or know how) these changes can be logged by the mail_log
plugin. Is it possible to log flag changes done by the pop3 session?
