Commas and spaces are treated identically, therefore
this is equivalent to:
smtpd_client_restrictions =
check_helo_access pcre:/etc/postfix/helo_access.pcre
regexp:/etc/postfix/helo_access.regex
The syntax on the last line was deprecated, and was removed from
the manpage. For backwards compatibility, if you omit the
check_xxx_access before a table, then the kind of access is determined
by the smtpd_xxx_restrictions type.
Therefore the above is equivalent to:
smtpd_client_restrictions =
check_helo_access pcre:/etc/postfix/helo_access.pcre
check_client_access regexp:/etc/postfix/helo_access.regex
