Re: [IMail Forum] ideal config

[Len Conrad]

I haven't a clue - hence the post to this list.

fair enough

Beats me. If neither iMail or the OS would benefit from it, might as well
remove it.

no! The cache speeds disk i/o throughput (it's more important the CPU MHz), so it's very important for the mailqueue, where the msgs files are typically very short-lived. the more cache the better.

No, but some of our switches are and all of them might be at some point.

ok, that's an extraneous reason, but harmless.

Beats me again. I'm not the main admin of the mail server (lucky for us I
guess :>).

everybody gets lucky sometime!  :)

 The sys log files are about 100MB per day with a lot of options
being logged. The iMail folder is about 8.8GB with 45,000+ files and 8,800+
folders.

you mean that's the mailbox directory tree?

to count mailboxes in the mailbox tree

dir /s \path\to\mailboxtree\*.mbx | find /c ".mbx"

I suppose there's something more efficient, so I guess we'll here from Sandford on that one! :))

 I've no idea how our configuration and volume compares to others -
I'd be curious to hear though.

take a previous days's sysMMDD.txt log file

find  /c "ldeliver" /path/to/sysMMDD.txt    ( is incoming msgs)
find  /c "rdeliver" /path/to/sysMMDD.txt   ( is outgoing msgs)

... roughly, but close enough for all intensive porpoises.

The current hardware RAID 5 SCSI (64MB cache) is getting beat to death with
out current traffic.

ok, going to multiple disks will help. Another SCSI controller+cache will also help. Quad 10 GHz Xeons WON'T help, unless your machine room is TOO COLD. :))

We were thinking about using LSOFT as a gateway to offload the SMTP traffic.
Any thoughts on that idea?

A great product, a huge rental price, but the idea is correct. IMGate is free (but if "free" means "bad" to your manager, I can solve that problem FAST!! :))
