POP Collector Screenshot

POP Collector is a freeware utility that downloads email from one or more POP3 mailboxes and forwards them to an SMTP server.

Key features:
* Supports global mailbox (with failsafe). You can use a catch-all mailbox with your ISP to collect all the mail for your domain. It will be sent to the correct recipient by POP Collector (except when recipient is in BCC field, which is not included in email headers).
* Unlimited POP3 email account support (maximum supported accounts is entirely dependent upon your operating hardware).
* Multiple domain support. You can download email from as many domains as you like.
* All settings are customizeable per POP3 mailbox. You can check the POP3 mailbox at any interval starting from 1 second (though this is HIGHLY inadvisable).
* Each POP account can have it's own SMTP server. POP Collector can now act as a router between many email systems.
* SMTP AUTH support (currently AUTH LOGIN, further methods may be added on request).
* Message validity checking. Optionally you can enable (per POP mailbox) the checking of each downloaded message to ensure it is compliant with RFCs. In some (few) cases POP servers return slightly malformed mail, which an SMTP server may or may not handle correctly. Any header lines that are not compliant are removed.
* Messages will be retained on the POP server until successful delivery or a permanent error (5.x.x) is reported by the SMTP server.
* Messages can be kept on the server for any length of time after successful delivery.
* Mail archive facility. All received mail (whether successfully forwarded or not) can be stored to a folder. This is disabled by default, as the folder can get very large if not monitored.
* Will run as a service on Windows 2003 or XP.
