Our email operations group manager put together a summary of our cyrus 
implementation recently for a meeting we have yearly with several 
other Universities.  It has links to the scripts we use, the caveat 
being they are all written for our environment and likely wouldn't 
run at another site the way they are currently.  However, they 
probably wouldn't be too difficult to port.

That's getting a bit OT but - why exactly is it so bad?
Slow bloated cow - maybe, but apart from that it can be configured to run
almost maintenance free. We are running it with spampd
(http://www.worlddesign.com/index.cfm/rd/mta/spampd.htm) and it tags more
than 99% of spam as spam and it does so for may years.

Simon

I don't know what I'd do unless there was a specific problem or issue.
Of the cuff my thoughts are:

1.) Make sure you are using Skiplist and not Berkley DB for databases
that default to Berkeley.
2.) Enable delayed expunge and configure a cyr_expunge job
3.) Disable, shoot, and burn SpamAssassin; that slow bloated buggy cow
isn't worth the resource and maintenance cost for the very small
improvement in SPAM prevention it offers over just RBLs, good MTA
configuration, and greylisting.  All of which are simple and low
[resource] cost.  Absolutely nothing else will do more to improve
performance.
4.) Make sure you have directory hashing enabled
5.) Disable atime on your mail store and meta-data store filesystems.
If using ext3 then investigate the data= options as well.
6.) Test your backup/restore procedure.
7.) Take a look at the Cyrus chapter of WMOGAG

Help with tweaking complete mail setup based on Cyrus + Postfix + MySQL

[Nybbles2Byte]

Hello ,

Well, I finally got the whole email setup working. The system comprises of:

OpenSuSE 11.0
Cyrus-Imap
Cyrus-SASL
Postfix
MySQL
Amavis
  SpamAssassin
  ClamAV

setup up to work with multiple domains.

I am sure that there are a bunch of little tricks that would make this system 
sing that an experienced administrator would know, and that would take me 
months to find out.  So, is there someone there, knowing that all the initial 
setup has been done and works, that could/would shell into my server and just 
tweak whatever he can with his experience.

While I am a single consultant working from home, I do realize that this should 
be paid for so a quote/estimate is welcome.  I just think it would be worth it 
to have an expert eye fine tune the system.

I'm not sure if this is the best place to ask this question and if not, a 
pointer to the right place would be appreciated.

Cheers!
