Is this map type (pcre) intended?
/etc/postfix/
main.cf:
smtp_discard_ehlo_keyword_address_maps =
pcre:/etc/postfix/discard_ehlo_keywords
/etc/postfix/discard_ehlo_keywords:
# This is likely to be incomplete.
216.32.0.0/16 silent-discard, pipelining
213.199.0.0/16 silent-discard, pipelining
65.55.0.0/16 silent-discard pipelining
94.245.0.0/16 silent-discard pipelining
Not that this workaround is needed anymore, but sometimes it's easier to
copy/paste old solutions than think them up anew.
