SMTPSADD is the default server address for the $SndMail function. You can specify SMTPSADD as:

  • Domain name of up to 255 bytes

    If the first character of the address is an alphabetic character (A to Z), it is automatically evaluated as a domain name.

  • Internet Protocol (IP) address, IPv4 format, in dotted decimal notation
  • (z/OS only) Internet Protocol (IP) address, IPv6 format, in colon-separated notation

On z/OS systems, the SMTPSADD parameter supports IPv6 network addresses. Symbolic names, such as CCAMVS1, are looked up using the GETADDRINFO service, which is capable of returning IPv6 addresses. For more information on specifying IPv6 network addresses, see the $SndMail M204wiki page.

You can override SMTPSADD for a specific call by entering a different value in the EMAILD parameter of the $SndMail function call.
