To read and send email from an email client, (e.g. Microsoft Outlook, Thunderbird or eM Client) requires the client to be configured and connected to MailEnable. The POP3/IMAP and SMTP server should be the server name that is running MailEnable. Email clients have to be able to resolve this server name to an IP address.
The username needs to be the full logon name for the mailbox. Remember that this is formatted as mailboxname@postofficename. Email will not be able to be retrieved if the full username is not used, unless a default post office has been specified. See the General configuration section for more information on specifying a default post office.
