Description

The TCP/IP option in use, either IPv6 or IPv4 addressing. The value of TCPOPTS is set by Model 204 based on the addresses that you supplied for the SMTPCADD and SMTPSADD parameters (specifying the SMTP client and server default addresses).

The values for TCPOPTS are described in the following table.

ValueDescription
X'00'SMTP is an IPv4 address (both the SMTP client and server addresses are in IPv4 format). This is the default.
X'01'SMTP client is an IPv6 address.
X'02'SMTP server is an IPv6 address.

The settings can be combined; X'03' indicates that both the SMTP client and server addresses are in IPv6 format.

For more information, see SMTPCADD: SMTP client address and SMTPSADD: SMTP server address.
