  • Short Name: The common, short name of the email service. If it has no shorter name, leave blank.
  • Preferred: If the provider offers multiple mail access methods, which one is better. Leave blank if there is no reason to prefer one over the other except for the technical merits of each protocol. If in doubt, leave blank.
  • Server Names: Include port numbers after server names (separated by a colon) if and only if non-default for (service + encryption type). But do check if port 587 is supported for SMTP and, if so, list it; it’s preferable to 25.
  • Encryption: SSL is SSL 3, TLS is TLS 1. Don't put anything if the server only supports STARTTLS; it's no good for security.
  • Usernames: "email" for the whole email address, "localpart" for the part of the email address before the "@" (e.g. fred in, or "prompt (D1234543)" to get the client to prompt, giving the example username "D1234543".
  • Enable URL: Some providers do not provide IMAP or POP service by default, but require it to be enabled via a web UI. Paste the URL that a logged-in user would use into this field, and the application can prompt the user to visit it.

Secure Auth

This is whether the password must be sent in clear or can be encrypted (hashed via MD5).

To find out manually, you can contact the server directly and talk the POP/IMAP/SMTP protocol manually. Use netcat -v hostname port (preferred) or telnet hostname port as "client".

  • POP3: when you see +OK WEB.DE POP3-Server or similar, enter CAPA, hit return.
  • IMAP: when you see * OK mwinf2j04 IMAP4 server ready or similar, enter 1 CAPABILITY, hit return.
  • SMTP: when you see 220 GMX Mailservices ESMTP or similar, enter EHLO, hit return.

In all cases, if you see CRAM-MD5 or DIGEST-MD5 in the response, the server should support "secure auth". If you only see AUTH LOGIN and/or PLAIN, the server probably does not support secure auth.
