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
Test::POP3 - Automate Email Delivery Tests SYNOPSIS
use Test::POP3; my $pop = Test::POP3->new({ host => $host, user => $user, pass => $pass, }); # this will delete all messages from the server ok($count == $pop->wait_for_email_count($count,$timeout),"got $count"); # find and delete a single email message which matches these rules # see Test::Email for more information $pop->ok({ # optional search parameters to => ($is or qr/is like/), from => ($is or qr/is like/), subject => ($is or qr/is like/), body => ($is or qr/is like/), headername => ($is or qr/is like/), }, "got message"); ok($pop->get_email_count() == $count, "$count emails in cache"); # get the Test::Email object my @email = $pop->get_email(); ok($pop->delete_all() == 2, "deleted 2 messages"); # tweak MIME::Parser settings my $parser = $pop->get_parser(); DESCRIPTION
Please note that this is ALPHA CODE. As such, the interface is likely to change. This module can help you to create automated tests of email delivered to a POP3 account. Messages retrieved from the server but not yet matched by a test will be cached until either that message is the first to pass a test, or is returned by "$pop3->get_email()". Messages returned are Test::Email objects. METHODS
"my $pop = Test::POP3->new($href);" The arguments passed in the href are host, user, and pass. "my $count = $pop->wait_for_email_count($count, $timeout_seconds?);" Calling this method will result in all messages being deleted from the server. This will wait up to $timeout seconds for there to be $count unprocessed messages found on the server. After $count or more messages are found, or after $timeout seconds, the current email count will be returned. $timeout_seconds defaults to 30. "my @email = $pop->get_email();" Get all of the email messages currently in local cache. You should call "$pop3->wait_for_email_count($count)" before calling this method if you think that there may be messages on the server yet to be retrieved. Calling this method will cause the local cache to be emptied. Email messages returned will be Test::Email objects. "my $count = $pop->get_email_count($check_server);" This will return the number of email messages in the cache. If $check_server is true, then the server will be checked once before the count is determined. If you would like to wait for messages to arrive on the server, and then be downloaded prior to counting, use "$pop3->wait_for_email_count()". "my $ok = $pop->ok($test_href, $description);" Calling this method will cause the email in the local cache to be tested, according to the contents of $test_href. The first email which passes all tests will be deleted from the local cache. Since this method only checks the local cache, you will want to call "$pop3->wait_for_email_count()" before calling this method. "ok" will produce TAP output, identical to "Test::Simple::ok" and "Test::More::ok". "my $parser = $pop->get_parser();" Test::POP3 uses MIME::Parser to process the messages. (MIME is not yet handled by "Test::Email", it will be soon.) Use this method if you want to manage the parser. EXPORT
