TCP/IP-channel-specific options: CUSTOM_VERSION_STRING (string)
Use of this option is NOT RECOMMENDED! This SMTP server option (not supported by the LMTP server) sets the IMTA version string to advertise on the SMTP server's 220 banner line. By default, the string "Oracle Communications Messaging Server <version-number> (<build-date>)" is used. This option is thus a complement to the (also not recommended)
received_version MTA option.
