Mail Forward allows you to forward mail from AOL, Gmail, Hotmail, MSN, Netscape, and Yahoo web mail accounts to any e-mail address. Standard POP and IMAP e-mail accounts can also be forwarded. Mail can be forwarded for up to 20 separate accounts. For each account, a forwarding address can be specified or a default destination can be used.

Mail Forward works by accessing your e-mail account Inbox and forwarding each piece of mail through your SMTP mail server. Mail that is successfully forwarded can either be deleted from the forwarding account mailbox or left on the server. The forwarding account address is used as the return address for the forwarded mail, so if the mail is undeliverable it will be returned to the forwarding account. A built-in scheduling feature allows mail to be forwarded automatically at a specified time interval.

Limitations:: The unregistered version of Mail Forward will operate for 30 days, and will show the Registration dialog each time you start the application.
