Email Server LANMailServer

LANMailServer allows sending and receiving emails within a local network, requiring only one computer with internet access. Using a conventional email program that supports the POP3/IMAP4 and SMTP standards, emails can be received and sent. It supports normal text emails, HTML format emails with or without file attachments. LANMailServer can be used with LAN connections and dial-up connections (Dial-Up Networking, T-Online Software).

Overview of Features

• Creation of local email accounts, including options for forwarding emails locally or to the internet, and an autoresponder function. (Shareware version supports up to 2 email accounts, with no forwarding options or autoresponder features.)

• Creation of email groups to consolidate email accounts, allowing emails to be sent directly to the group rather than to individual recipients.

• Emails can be sent within the network and to internet.

• Emails from external email accounts can be retrieved and assigned to local users. External email accounts supporting POP3/IMAP4 standards are supported. (Shareware version supports up to 2 external email accounts.)
