Configuring POP3 or IMAP4 mail server settings

Introduced in 2023.1

POP3 and IMAP4 mail servers enable users to access their messages from different devices while keeping the synchronized. This article describes the process of setting up a mail server using POP3 or IMAP4.

Before you begin:

  • If you plan to use an IMAP server, choose which folder the Mail Connector will monitor for incoming messages. By default, it is "INBOX", but you can create a subfolder, such as "INBOX.Support" or "INBOX/Support". Your mail server must be configured to route incoming e-mail messages to that folder.

  • If you plan to use an IMAP server for working with MS Office 365 mailboxes (e.g. outlook.office365.com), you can use only slash characters for the subfolders, such as "INBOX/Support".

To configure POP3 or IMAP4 mail server settings:

  1. Under Mail Server, choose the account type for incoming mail: Post Office Protocol v3 (POP3) or Internet Message Access Protocol v4 (IMAP4).

  2. In the Server Name field, type in the name of your incoming mail server. If the mail server uses a non-default port number, specify this port number in the Port field.

  3. For IMAP4: The Mail Box field is initialized with the default INBOX value. If you created a special subfolder the Mail Connector will be pulling e-mail messages from, type in its name.

  4. Enter the mailbox user name and password to connect to the mail server.

  5. If your mail server requires Security Password Authentication, select the Require Secure Password Authentication (SPA) check box.

  6. In the Secure Connection section, select one of the following options:

IMPORTANT: The current version of Alloy Navigator Express can establish a secure connection to a mail server using SSL 3.0 up to TLS 1.2.

    • None - This establishes an insecure (plain text) connection.

    • STARTTLS, if available - This establishes a secure connection using the STARTTLS extension if it is supported by the mail server. If the server does not support STARTTLS, an insecure connection is established.

    • STARTTLS - The Mail Connector will attempt to establish a secure connection using the STARTTLS extension. If the mail server does not support STARTTLS, a connection is not established.

    • SSL/TLS - The Mail Connector will attempt to establish a secure connection. If the mail server does not support SSL/TLS, a connection is not established.

  1. If you want to prevent communication with the mail server via a secure connection when a certificate validation error occurs, select the Reject invalid certificates check box.

  2. Click Test Connection to verify that the Mail Connector can connect to the specified mail server.
