I've tried to summarize the different ways of doing mail delivery in
a murder

There are some brief instructions on setting up lmtpproxyd to query
the localhost. Try those out and let me know if you have questions.

You're options are to
1. Have lmtpproxyd query the local server for each incoming message.
This decreases load on the murder master. You do this by creating a
config file for lmtpproxyd and setting murder master to the
localhost. Then you just need to get the auth setup.
Can you show me how to configure lmtpproxyd to use localhost as murder
master?
Thanks

Hi..
I'was thinking that Murder is a very good concept for cyrus...
Till today.
I've started some performance test:
I've 4 MTA with Postfix+Cyrus frontend 2.2.12
4 backend with Cyrus 2.3.6
and 1 Mupdate with cyrus 2.2.12.
I've started with smtp-stone sending
3000 msg (1000 for each of 3 users on 1 backend).
Backend load was very low.
But in this time mupdate have load about 1,5 (why ?)
The concept was that mupdate is only for changing location of
mailboxes... My frontend have information on mailboxes (checked
with
ctl_mboxlist -d) but they still are looking in mupdate which
causes high load
and SIGSEGV...
Which causes lmtpproxy to drop connecitons and growing queue in
postfix...
Am i doing something wrong ?
Authentication is doing by sasl digest-md5 to avoid SQL database
performance,
so i think this is no problem..
So why mupdate causes such problems ?
Thanks
AK
