If your ISP supports mail service, you can use SNDM as common mail client software (e.g. Outlook Express). All you need is name of the SMTP server at ISP, mail account, and direct TCP/IP connection to the SMTP server.
Having that said, there are cases when you cannot use SNDM with some ISPs:
- The mail server requires authentication.
- The mail server does not comply SMTP standards.
and so on.
I don't know why your ISP insisted to set the ALWRLY parameter of CHGSMTPA to *NONE, because it does not do any harm unless your system sends SPAM mails.
