2.24.2.4.4. Correct configuration of authentication in The Bat!

When a mail client connects to a mail server to receive or send mail, authentication is used for security purposes. There are different authentication methods. Some of the options are CRAM-MD5 or APOP, which are currently outdated and insecure. Here's how to check your current settings and set up a more modern and secure authentication method.

To correctly configure authentication in The Bat !, do the following:

  1. In the main window of The Bat! right click on the added mailbox and select "Mailbox properties…»:
  2. In section "Transport"In the block"Sending mail»Click«Authentication…»:
  3. Check the authentication settings for outgoing mail:
    • Checkmark opposite "SMTP Authentication (RFC-2554)"Must be installed.
    • The switch should be opposite "Use Mail Receive Options (POP3 / IMAP)».
    • Checkmark opposite "Require secure authentication» necessarily must be removed. If the checkbox is checked, uncheck it and save the changes.
  4. In the block "Receiving mail»Click«Authentication…»:
  5. Check the authentication settings for incoming mail. The switch should be opposite "Regular". If it is set opposite to a different value, change it to the specified one and save the changes:
  6. Check your encryption settings. The parameters “Compound"And"Port»:
    • Sending mail:
      • For the connection to the server to be encrypted, it is recommended to use the "Safe on spec. port (TLS)"And port 465.
      • If an unencrypted connection suits you, you can use the "Common"And port 25 or 2525.
    • Receiving mail:
      • If the IMAP protocol is used (opposite "Protocol"Indicated"IMAP4»):
        • For the connection to the server to be encrypted, it is recommended to use the "Safe on spec. port (TLS)"And port 993.
        • If an unencrypted connection suits you, you can use the "Common"And port 143.
      • If the POP3 protocol is used (opposite “Protocol"Indicated"POP3»):
        • For the connection to the server to be encrypted, it is recommended to use the "Safe on spec. port (TLS)"And port 995.
        • If an unencrypted connection suits you, you can use the "Common"And port 110.
  7. Save your changes and test your mail.

If everything is set up exactly as described above, but in authorization log when sending, the old authentication method is still mentioned, then there is nothing to worry about - The Bat! when sending, it automatically selects the most suitable method supported by the server, and after the CRAM-MD5 support is disabled, it should continue its work as usual.
