Setting up POP3 and dialup downloading

Post office protocol (POP3 (RFC 1225)) is a client/server protocol for storing email so that clients can connect to the POP3 server at any time and read the email. A mail client will make a TCP/IP connection with the server and by exchanging a series of commands, enable users to read the email. All ISPs support POP3.

The recommendation for GFI MailEssentials is to, if possible, avoid using POP3 and to use SMTP since POP3 is designed for email clients and not for mail servers. Notwithstanding this fact, and to cater for situations where a static IP address used with SMTP is not available, GFI MailEssentials can use POP3 to retrieve email.

1. Select POP2Exchange node and double click General item.

2. In the POP3 tab, select Enable POP2Exchange checkbox to enable POP3 downloader.

3. Click Add to add a POP3 mailbox from which to download email.

4. Key in the POP3 server details, mailbox login name and password of the mailbox. Choose between:

•	Send mail to address stored in ‘To’ field - GFI MailEssentials will analyze the email header and route the email accordingly. If email analyzing fails, email is sent to the email address specified in the alternate address field.

•	Send mail to alternate address: All email from this mailbox is forwarded to one email address. Enter full SMTP address in the ‘Email address’ field.

5. Provide the alternate address and click OK.

NOTE 1: When specifying the destination email address (the address where GFI MailEssentials will forward the email to), ensure that you have set up a corresponding SMTP address on your mail server.

NOTE 2: Multiple POP3 mailboxes can be configured.

6. In the POP2Exchange configuration dialog, configure other available options:

•	Do not download mail larger than (Kbytes): Specify a maximum download size. If email exceeds this size, it will not be downloaded.

•	If mail is larger, then: Choose to delete email larger than the maximum allowed size, or send a message to the postmaster.

1. Select POP2Exchange node and double click General item.

2. From the Dialup tab select Receive mails by Dial-Up or Dial on Demand checkbox to enable dialup.

3. Select a dial-up networking profile and configure a login name and password. The following options are available:

•	Use this Dial-Up Networking profile: Choose the Dial-up Networking profile to use.

•	If not connected dial: GFI MailEssentials will only dial-up if there is no connection.

•	Process only when already connected: GFI MailEssentials will only process email if a connection already exists.

•	Dial on demand router: In case of an internet connection that is automatically established (such as a dial on demand router) select this option. GFI MailEssentials will pick up email at the specified interval without triggering a dial-up connection.

•	Process every (minutes): Enter the interval at which GFI MailEssentials must either dial-up or check if a connection already exists (depends on whether you set GFI MailEssentials to dial-up or to only process email when already connected).

4. Click on Schedule and specify the hours when GFI MailEssentials should dial-up to pick up email. A check mark indicates that GFI MailEssentials will dial out. A cross indicates that GFI MailEssentials will not dial out at this hour.
