Mail Servers
I hate asking this, but I thought that this would be the fastest way to get the answer. I may be setting up a mail server for a factory. From what little I know so far, it will be for all a mail server for all five hundred employees. (one in each location) so they can check work related email. I was thinking about using woody, but have the following 2 questions. 1 What is the max user limit that woody + exim will support 2 Could someone point me to a good pointer / how-to for this. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

You'll have a lot less trouble in the long run IMHO. The changeover isn't really that painful either. Been a while since I dealt with qpopper, but wasn't the lock actually /var/spool/pop/.pop (the temporary copy of the user's mailbox)? If that's correct, mount /var/spool on a different partition from /var/mail, and only enable quotas on /var/mail. If you've got any load on the server, you'll want /var/spool, /var/log, and /var/mail on seperate drives for performance anyhow. -- _ Rich Puhek ETN Systems Inc. _ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

what do you do with detected relay attempts?
I have just realised that I wasn't getting postfix relay block alerts under my new postfix set up (on a small Email list system). So I've twigged the right setting and am now getting the very satisfying messages like: In: MAIL FROM:<[EMAIL PROTECTED]> Out: 250 Ok In: RCPT TO:<[EMAIL PROTECTED]> Out: 554 <[EMAIL PROTECTED]>: Relay access denied which, of course, has the IP address and sender name in the subject line of the alert to me. A quick check confirms that they are congruent so I think I should report it to the system. I currently report all spam I get to abuse.net and spamcop.net as I want the anonymity I think they given my reports. Now I'm not sure of the best way to report something like the above.

Re: upgrading just one "stable" package to "testing" version
I have done this to all except 2 of my stable servers, many of them
remotely.
The one problem is that the libc6 upgrade requires you to restart a few
programs (ie, exim, inetd, ssh). You may have other programs on the machine
that the upgrade doesn't detect, and must be restarted manually.
An easily solution is just to restart the entire machine.

The SSH in stable only supports version 1 of the SSH protocol; if you
configure your "testing" machine to accept that older version of the
protocol (by putting "Protocol 2,1" in /etc/ssh/sshd_config and restarting
ssh), SSH-ing from your stable machines works.

You'll need testing's apt (plus its depencencies) for that. The following
should work (though I'm not aware of people actually using this
configuration as most simply fully upgrade to testing, so you may want to
use the "-s" flag to apt-get to see what it intends to do before actually
doing these steps):
- add "testing" entries to /etc/apt/sources.list in addition to the entries
for "stable"
- "apt-get update"
- "apt-get install apt"
- create an /etc/apt/preferences with contents
Package: *
Pin: release a=stable
to have apt default to the stable versions
- install testing's ssh by requesting it explicitly:
"apt-get -t testing install ssh"

Re: upgrading just one "stable" package to "testing" version
OR... you could simply download the ssh testing deb file and install
that... (don't know what the dependencies are though).
