allowing others with dynamic IPs to use your email service.

if you are running pop3 and smtp and wish to allow others to have an email address using your service out side of your local network you may run into a problem; relaying should be disallowed for others out side of your private network, so how do you allow someone with an account that you gave them to use your mail service, without opening your server to be an open relay for anyone who wants to abuse it? this website: http://popbsmtp.sourceforge.net/

provides a great perl utility that will look at successful pop3 logins and then create a temporary database with that users ipaddress and user name. with that you can set your mail server, (postfix, sendmail...) to look at the database and will allow mail relaying for those that have successful pop3 logins. this utility works with various pop3 servers, and the website includes detailed instructions on just exactly how to set it up. all youll hav eto do i tell your users to CHECK their mail first before they try to send it.

NAME
rt-email-dashboards - Send email dashboards SYNOPSIS
rt-email-dashboards [options] DESCRIPTION
This tool will send users email based on how they have subscribed to dashboards. A dashboard is a set of saved searches, the subscription controls how often that dashboard is sent and how it's displayed. Each subscription has an hour, and possibly day of week or day of month. These are taken to be in the user's timezone if available, UTC otherwise. SETUP
You'll need to have cron run this script every hour. Here's an example crontab entry to do this. 0 * * * * /usr/bin/perl /opt/rt4/local/sbin/rt-email-dashboards This will run the script every hour on the hour. This may need some further tweaking to be run as the correct user. OPTIONS
This tool supports a few options. Most are for debugging. -h --help Display this documentation --dryrun Figure out which dashboards would be sent, but don't actually generate or email any of them --time SECONDS Instead of using the current time to figure out which dashboards should be sent, use SECONDS (usually since midnight Jan 1st, 1970, so 1192216018 would be Oct 12 19:06:58 GMT 2007). --epoch SECONDS Back-compat for --time SECONDS. --all Ignore subscription frequency when considering each dashboard (should only be used with --dryrun for testing and debugging) perl v5.14.2 2013-05-22 rt-email-dashboards(8)
