$o
Token separation operators V8.6 and earlier
Prior to V8.7, the $o macro stored as its value a sequence
of characters, any one of which could be used to
separate the components of an address into tokens.
That role has been taken over by the V8.7 and later
OperatorChars
option (OperatorChars on page
1062).
For backward compatibility, the $o macro is still
honored by V8.7 sendmail in
preversion 7 configuration files (The V Configuration Command on page
580). Otherwise, it is unused in version 7 and later
configuration files.
