Hi Marc.
I'll see what I can do about testing this version & getting some accurate
results. I don't run the IMAP servers here @ Cornell and it will take a
bit to co-ordinate the effort.
Thanks for the info & bug fix!

Hello,
I did a little research and found out that we did not cache the
mailbox-list we retrieved through LSUB calls.
This means we did a LSUB request on almost each page load for information
we should have cached.
The caching was broken and reintroduced again 10 minutes ago. The changes
are in SM

Not only is SIEVE a better alternative overall, it has been theorized that
the message_filters plugin is the main reason for the current
"chattiness". I haven't had time to look at the plugin yet.
Hmm, 10K users shouldn't be a problem for a V880 of this magnitude.. we have 4 cpu
420Rs with 4GB of RAM doing this for 8,500 users and the load average hovers around
0.30, so I'm betting unless you have a wildly abusive user base (not uncommon in the
University setting!) some tuning may definitely

Lee,
I've been following some of your postings reguarding SM and Cyrus.. I don't
claim to have the solution to your troubles, but here at TI, we have a similar
setup and I wanted to ask you how Cyrus is configured in your installation.

My apologies for the extreme length, but I do want to include what
information I have.
When Cornell upgraded from SquirrelMail v1.4.1 from v.1.2.11, our IMAP
servers started to buckle and die under the load from the increased IMAP
traffic. This server is no slouch (Sun VX880 w/8 processors & 32G R
