I have been trying to post to this list using my original subscriber
email address.
Unfortunately, It has been not possible up to now.
I am using a personal and secondary address to workaround a dumb rule,
assuming that all hosts under a dynamic IP is a source of spam.
My office server IP is NOT dynamic, but is part of a Brazillian ADSL
range.
Sorry bothering you all with such matter but I wasn't able to quickly
locate an admin address and I HOPE this message get attention from
someone able to workaround my issue.
Regards.
The only good solution is to use your ISP's email facility for forwarding
email. If you post directly from a dialup address you will find a whole
host of sites that block your emails. Postings from dialup DSL addresses
are almost always spam. The exceptions are so few that blocking dialup
addresses or dynamically assigned addresses is catching on throughout
the Internet.

It looks like you may need to yell at your isp to get you unlisted. It
looks to me like they listed their block to enforce some policy (many do)
This raises another question from me,
my inet ip is 65.113.179.82
rdns of this yields: 65-113-179-82.dia.cust.qwest.net
Now, I don't clam to be an expert, but where in that does it say
'dynamic' to anyone? If you want to post to aol, your HELO MUST match
your rdns (has been in my case and a few others.)
Absolutely incorrect! Your HELO/EHLO must match your rDNS or the
rDNS needs to match an MX RR for your argument or a few other cases. AOL
is quite strict, but you have misinterpreted either their stated policy
and/or RFCs 2821 and 2822. In particular, you can note that since I use
dynamic routing, the HELO/EHLO argument from this message is "plectere.com"
which has no 'A' RR and hence no rDNS. The client adress used, however
will be smtp.mpa0.plectere.com which does have an 'A' record and does have
both rDNS and FCrDNS poperly setup (and while irrelevant to this discussion,
also is listed in the SPF record for plectere.com and is a 'MX' for the domain
plectere.com).
I believe that all that AOL requires is that the client's IP match
its rDNS; You can easily check by writing their support staff - they are
amazingly good and helpful and certainly can better explain the exact rules
than I can; I can tell you, I have no difficulties seding mail to AOL and
my HELO/EHLO argument does not match the client rDNS.
Actually incorrect, too.
AOL, and many other large ISP's do indeed subscibe to a blacklist for
ip addresses listed by other ISP's as "dynamic" addrsses. I am forced
to relay through my isp's smarthost for outbound mails, even though my
EHLO domain matches my DNS domain fully.

Now, back to the task at hand...
My home ip address is
67.34.142.208
rdns of it is adsl-067-037-142-208.sip.mco.bellsouth.net
I called and asked what each part of this means
adsl-ip (duh)
sip = static ip (true)
mco = Melbourne Cocoa Orlando (telephone area)
bellsouth.net (duh)
now, this an asdl res address, but by quickly looking at that you can't
tell if it's biz or res. Now, I know this because a friend of mine has
the exact same connection (adsl static 3mb/384kb) but biz connection
(btw, bellsouth blocks 25in and out for res connections, not biz
connections.) I'm not going to provide his ip or rdns (they are his, not
mine to play with :-D ) but his rdns is the same setup adsl-ip
.sip.mco.bellsouth.net. The biggest difference, I'm listed as res ip,
and he's not (Bellsouth policy.) Would my friend be blocked because of
the 'adsl-ip.sip.mco.bellsouth.net'? If so I may need to look to a
different isp before I start my biz.
Now, back to here (work) rdns info
Obviously that's a Cust Qwest ip address
i haven't called to get what dia means,
Now, before someone says "hey, dia means dialup" ok.. that would be true
IF this was dialup, but it's not.
It's full T1 with VoIP (running on a separate ip address)
Currently when I send to this list I see HELO_DYNAMIC_IP from the list
apache mail server(s).
The question here... Should I be pressuring my ISP to change my rdns to
trusswood.net (our domain here) or just not bother ie, is there any real
damage that could be done?
Many ISPs will not delegate for a single address; If you pay for
more than one IP, you should call and have rDNS delegation setup (most
ISPs use similar, but slightly different conventions). If you only have
a single static IP, they likely will not change rDNS for you, but should
move you to a block marked as static. Also, if BellSouth is like most
of the other telcos, you can have the port 25 block removed, but it may
take a few telephone calls to get to a person who can understand why *and*
how (I say this as someone who has a SBC residential line with a static IP
and no port 25 block, which only took about two hours to reach a correct
department and person to setup - BTW. no charge for either, but the first
6 or so people tried to get me to change to a business account before
getting some who understood the issues).

P.S. I have several incoming DSL lines and nearly every provider has
willingly treated my account(s) as special - It just takes getting to
the correct department/group/person to get it done.
