only half of the problem solved -- cyrus deliver slow

[Su Li]

Thanks Scott,

I am thinking of switching to postfix. I hear a few things about it too.
Maybe I have to bug you some later time. But the bottle neck right now seems
like the imap server.

For "enable lmtpunix", I tried add the following line to imapd.conf:
lmtpsocket: /var/imap/socket/lmtp

But I still get: " cyrus  9425  9418  0 14:28 ? 00:00:00 deliver -e -m  --
loadtest641".

There must be something else I need to change to enable lmtpunix, and not to
use /cyrus/bin/deliver.
Should I do something in sendmail config file -- in your case postfix config
file?



Any one knows how to set up sendmail for lmtp socket delivery so that I
don't get lots a deliver -e -m in the system?


Thanks,

Su

I'm not a sendmail user, I use postfix instead. It's easier to
configure and maintain. It's well supported, has an active mailing
list, good docs,  and in general it 'just works'.

If you're spawning /usr/cyrus/bin/deliver processes as it appears in
your ps listing then yes, that's going to hurt you.

In your cyrus.conf enable lmtpunix: socket and configure sendmail to
deliver directly to the socket, not use the deliver binary.

If you want to switch to postfix let me know. I'll help you configure
it. For sendmail you should ask someone else on this list, or the
sendmail list, how to setup sendmail for lmtp socket delivery.
