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
ftpmail - FIFO-based Perl script for sending email based on proftpd TransferLog SYNOPSIS
ftpmail [ --help ] [ --fifo fifo-path ] [ --from email-address ] [ --log xferlog-file ] [ --recipient email-address ] [ --subject email- subject ] [ --smtp-server server-address ] [ --attach-file ] [ --auth smtp-auth-info-file ] [ --ignore-users regex-pattern ] [ --watch- users regex-pattern ] DESCRIPTION
ftpmail is a Perl script designed to read ProFTPD's TransferLog log entries, watching for uploads, and to send an automatic email notifica- tion when uploads occur. To use ftpmail , you configure your proftpd daemon to write its TransferLog to a FIFO; the ftpmail program is a FIFO reading program which then processes those log messages. OPTIONS
--help Display a short usage description, including all available options. --attach-file If used, this will cause a copy of the uploaded file to be included, as an attachment, in the generated email. --auth smtp-auth-info-file Configures the path to a file containing SMTP authentication information. The configured file should look like this: user username password password --fifo fifo-path Indicates the path to the FIFO to which proftpd is writing its TransferLog. That is, this is the path that you used for the TransferLog directive in your proftpd.conf. This parameter is REQUIRED. --from email-address Specifies the email address to use in the From email header. This parameter is REQUIRED. --ignore-users regex-pattern Specifies a Perl regular expression. If the uploading user name matches this regular expression, then an email notification is NOT sent; otherwise, an email is sent. --log xferlog-path Since this script reads the TransferLog using FIFOs, the actual TransferLog file is not written by default. Use this option to write the normal TransferLog file, in addition to watching for uploads. --recipient email-address Specifies an email address to which to send an email notification of the upload. This option can be used multiple times to specify multiple recipients. AT LEAST ONE recipient is REQUIRED. --smtp-server server-address Specifies the SMTP server to which to send the email. This parameter is REQUIRED. --subject subject Specify a custom Subject email header for the email sent. The default Subject is: User '$user' uploaded file '$file' via FTP --watch-users regex-pattern Specifies a Perl regular expression. If the uploading user name matches this regular expression, then an email notification is sent; otherwise, no email is sent. FILES
