[Dovecot] RFE: please add mail queue id to 'sent vacation response' log line

May I ask to add receiving smtp server mail queue id to sieve 'sent vacation response' log line?

Now:

2014-05-09T15:04:32+02:00 name/ip dovecot: lmtp(8164, user1@domain): YvJFLVbSbFPkHwAASpgOhg: sieve: msgid=<000301cf6b87$36be4570$a43ad050$@us.edu.pl> size=46850: sent vacation response to <user2@domain>

Asked for something like this:

2014-05-09T15:04:32+02:00 name/ip dovecot: lmtp(8164, user1@domain): YvJFLVbSbFPkHwAASpgOhg: sieve: msgid=<000301cf6b87$36be4570$a43ad050$@us.edu.pl> size=46850: sent vacation response to <user2@domain> (smtp:[ip]:port): 250 2.0.0 Ok: queued as mailqueueid) <<<

In case there are more than one vacation response recipients there is no way to identify who had received the response and who hadn't.

Thanks.
