only half of the problem solved -- cyrus deliver slow

[Su Li]

Thanks Larry,

I followed http://www.tldp.org/HOWTO/Cyrus-IMAP-7.html to setup my sendmail.

  MAILER(local)
  MAILER(cyrus)
  define(`confLOCAL_MAILER',`cyrus') 
  LOCAL_RULE_0
  R$=N                   $: $#local $: $1
  R$=N < @ $=w . >       $: $#local $: $1
  Rbb + $+ < @ $=w . >   $#cyrusbb $: $1

One thing I don't understand is how do I not use "deliver". Right now, when
the system is running, I got from ps -ef|grep deliver: 

cyrus    23916 23915  0 19:50 ?        00:00:00 deliver -e -m  --
loadtest4707
cyrus    23921 23920  1 19:50 ?        00:00:00 deliver -e -m  --
loadtest1400
cyrus    23924 23923  0 19:50 ?        00:00:00 deliver -e -m  --
loadtest1554
cyrus    23931 23930  0 19:50 ?        00:00:00 deliver -e -m  --
loadtest651
cyrus    23934 23933  1 19:50 ?        00:00:00 deliver -e -m  --
loadtest3352
cyrus    23939 23938  0 19:50 ?        00:00:00 deliver -e -m  --
loadtest2848
cyrus    23943 23942  0 19:50 ?        00:00:00 deliver -e -m  --
loadtest2943

Is that the "deliver" you mean? If yes, how do I diable it?

For "deliverymode=queue", I changed in /etc/sendmail.cf. After that when I
send mail, I can not get it, unless I restart sendmail. Any thing else I
should do?

Thanks,


Su

What version of Sendmail are you using? You want Sendmail 8.12.4 or
later. You should consider running Sendmail in deliverymode=queue with
frequent queue runs if you want the best possible performance. (Take a
look sendmail/TUNING in the Sendmail distribution.)

You should also configure Sendmail as described in the Cyrus
documentation, using LMTP delivery to Cyrus. You don't want "deliver"
processes---it's a completely unnecessary fork.

There's an Addison Wesley book on "sendmail performance tuning" soon
to come out that might help you with this. I'm going to be receiving a
review copy and I'll report on it.
