Just in case these might one day go into the specs without checking:
In NewStuff (from 4.12):
49. Some new features have been added to the ACL facilities:
(i) The new verb "drop" behaves like "deny", except that the SMTP
connection is forcibly closed after the 550 error message has been
sent. For example:
drop message = I don't take more than 20 RCPTs
condition = ${if > {$rcpt_count}{20}}{yes}{no}}
the condition has got an extra } after the 20.
later:
deny message = Too many bad recipients
condition = \
${if and { \
{gt{$rcpt_count}{10}} \
{ \
lt \
{$recipients_count} \
{${eval:$rcpt_count/2}} \
} \
}{yes}{no}}
the "gt" and "lt" operators do not exist and should be replaced by
">" and "<" (sorry for the obvious remark). Or is this a preview of
things to come?
