MailEnable Standard Guide
POP - General

The following table outlines the configuration options for MailEnable’s POP service:

Setting

Description

Maximum concurrent connections

The number of concurrent connections from email clients that the service will allow.

Alternate @ characters

Some older mail clients don't allow the use of @ in the username section. Since the MailEnable usernames are formatted in mailboxname@postoffice format, this may cause problems. To solve this, MailEnable can specify the characters that can be used as a substitute. Just enter the list of characters such as #$%. This will allow users to log on using mailboxname@postoffice, mailboxname#postoffice, mailboxname$postoffice and mailboxname%postoffice.

POP Port

The port MailEnable will allow client POP connections on. The default is 110.

Also listen on alternate port

Allows the POP service to listen on an alternate port. Usually this is done to cater for clients who may be on connections where their outbound port 110 has been blocked.

Enable APOP authentication

Usually, the users’ username and password are sent in clear text format (i.e. not encrypted). Enabling this option will force clients to enable APOP authentication on their mail client software. Make sure users are using software that supports APOP, otherwise they will not be able to receive email. Some older mail clients do not support APOP.

Timeout for idle connections

If this setting is enabled, and a client connection has been idle or not passed any commands to the server for a set period of time, the connection will be dropped by the server.  Timeout setting is in seconds.

Access Control

The Access Control feature can specify who can connect to the POP service. A list of IP addresses that are either banned from connecting, or are the only ones allowed to connect by selecting the Access Control button can be specified.

IP Addresses to bind POP to

It is possible to select the IP addresses that the POP service will be bound to. On a multi-homed machine you may only wish to allow connections on particular IP addresses. ‘Always bind all IPs’ will allow connections on all IP addresses that are configured for the machine.
