The ATSIGN statement in the hlq.SMTP.CONFIG file has been set. Setting this statement means that SMTP will use this character instead of the at sign (@) between the user ID and host ID fields in addressing strings, for example, userid@hostid. This statement should only be used for specific languages because of translation encodings.

Setting this option might cause problems if notes are being sent between different language sites.

symbol is the input symbol replacing the at sign (@).

For more information about the ATSIGN configuration statement, see the z/OS Communications Server: IP Configuration Reference.
