Hello all,
Edwin Casimero question about the Qmailtoaster's specifications for
serving
10,000 email clients spur my first question.
1. I am setting up a Qmailtoaster for 25 email clients but expect
the
number won't increase to 50 anytime soon, if ever. Have I assumed
correctly
that the standard install of Qmailtoaster is sufficient given the correct
hardware and internet connection for this application.
2. I want to setup the above 'system' for POP3-SSL clients using
Outlook and Outlook Express (OE) and let individuals take care of backing
up
their own email. If I decided to us IMAP4 or IMAP4-SSL is there a rule of
thumb mailbox size.
3. If I use POP3-SSL is there a way besides setting up IMAP4 or
IMAP4-SSL accounts for each user, or even a single account, to feed spam
back to the server? I've been investigating this and have found that
forwarding to a [EMAIL PROTECTED] or [EMAIL PROTECTED] account changes the
header of the email and 'resend' using Outlook does pretty much the same
thing as a forward. Outlook and Outlook Express are the email client
software this particular customer will be using.

QmailToaster standard install should handle this spec. I would think any
PC under 5 years old with say 512M memory could handle it. More CPU, more
memory, more better! Hard drive will depend on how much room you want for
each user. Using IMAP, I would go with 20-30G for the system and lots of
extra space for the uses, say 50G. Always overbuild. I am going
completely from the cuff here, no expert.
I had a similar problem with spam reporting. I found an address just does
not do a good job. I ended up using Spam Buttons in SquirrelMail, which
provides a pipe to your command line script. That may not work for you,
b/c you need Outlook to work. I would suggest having the users place the
email in a IMAP spam folder then having a cron job pick up, process, and
delete them.
I'll 2nd this suggestion. I've set up shared ham/spam IMAP folders, and
have a nightly cron job run to sa-learn then delete their contents.
Users simply move ham/spam to the appropriate folder.
Here's the cron job:
#!/bin/sh
#####################################################################
# learn and remove spam and ham in shared folders
#####################################################################
# shubes 3/26/08 - created
#####################################################################
learndir="/home/vpopmail/domains/mydomain.com/sa-learn"
hambox=.Ham
spambox=.Spam
do_the_learning(){
learnas=$1
maildir=$2
shopt -s extglob
for spamfile in `find $maildir/+(cur|new)/* 2>/dev/null`; do
sudo -u vpopmail -H sa-learn --$learnas $spamfile
rc=$?
if [ $? != "0" ]; then
echo "sa-learn failed, rc=$rc, spamfile=$spamfile"
exit $rc
fi
rm $spamfile
done
}
do_the_learning ham "$learndir/$hambox"
do_the_learning spam "$learndir/$spambox"
exit 0
</end script>
