Try e1.ru instead of el.ru ;).

Cheers,
Corrected to '*.el.ru'

Not that it matters - with rejection on PTR RR fail or reverse_host_lookup that 
rule has about a 1 in 100,000 chance of ever being triggered *here* (not a lot 
of legit traffic in our direction form there anyway...).

Couldn't do forward-reverse lookup fail in such a hard-edged manner five years 
ago. So-called 'false positives' were overwhelming.

No longer problematic at all.

As the 'big' ISP have had to take a similar route, *honest* folks have gotten 
the message:

- register a PTR RR & MX or A to *match*, AND NOT in dynamic-IP block

- OR use a 'smarthost'

- ELSE .... well .. a lottery ticket at least has *some* chance of a win...
