I'm not sure, but will this fix the problem?  It's from the IBM AIX sendmail.cf.
This seems to imply that the 'at' must have whitespace on both sides of it to be
processed into a '@'.

#
#  Turn an "at" token into "@".
#
#  The I macro specifies space or some equivalent char defined by the OI
#  config option above.
#
R$+$Iat$I$+             $:$1@$2                         "at" -> "@" for RFC 822
