Definition
property AuthType: TSmtpAuthType;
Inherited from TCustomSmtpCli.AuthType
Description
Property AuthType specifies the authentication method to be used with method Auth. Authentication is necessary to login in the mail server as you're otherwise not allowed to send any e-mails. Most internet service providers require some sort of authentication. The list of possible values below contains such methods like username password without sophisticated encryption or checksum or stronger methods which use MD5 or Sha1 hash algorithms.
Possible values are:
smtpAuthNone, smtpAuthPlain, smtpAuthLogin, smtpAuthCramMD5, smtpAuthCramSha1, smtpAuthAutoSelect
Most of them are self-explaining, except smtpAuthAutoSelect which causes the component to perform a smart detection of most secure authentication method possible.
Example
SmtpCli1.AuthType := smtpAuthAutoSelect;
Best practices
Recommended setting is smtpAuthAutoSelect.
