Some email programs let you specify
the authentication method - the typical authentication
types are:
Authentication
Method
Compatibility
PLAIN / PLAIN TEXT
CRAM-MD5
DIGEST-MD5
NTLM
Of these we would recommend CRAM-MD5
- if that does not work try DIGEST-MD5 or PLAIN TEXT.
NTLM authentication is not currently compatible with
AuthSMTP.
