a list I use. (It's not totally public).
It catches a LOT of the junk from bad-looking rDNS.
I'll ask if I can reveal details.

Marc Perkel,
Your junkemailfilter.com server that does the sender verify has
what looks to be dynamic/generic rDNS. This causes MY server to
reject your sender verify:
Nov 8 08:12:24 thebighonker exim[32310]: H=5.ctyme.com
(pascal.ctyme.com) [69.50.231.5]:35579 I=[192.147.25.65]:25
F= <
mailto:sender-verify@junkemailfilter.com>
<sender-verify@???> rejected RCPT
<
mailto:ler@lerctr.org> <ler@???>: EL: () in EL list
Can you get the rDNS to be more legitimate?
Thanks,
Larry Rosenman
(Sorry for taking THIS lists bandwidth, but I know Marc is on it, and
I can't email him Directly because of this).
Well, the reverse lookup is 5.ctyme.com - I suppose I could change
that but why do you think it's dynamic?
Dynamic/Generic (I.E. it looks like just a generic place holder).
So would five.ctyme.com also trigger your filter, Larry (assuming that both
A and PTR were changed)? There isn't exactly a huge difference between the
names 5.cytime.com and five.cytime.com.
1) the pattern *WAS* [0-9]+.ctyme.com
2) it's been removed.
That's interesting - where did this pattern [0-9]+.ctyme.com come from
originally?
