The (static) IPv4 address of my computer is 63.195.85.27 which maps
to adsl-63-195-85-27.dsl.snfc21.pacbell.net
Forward and reverse lookup match; sendmail will not complain about
the mapping (BTW: I'm the sendmail maintainer, so I know a bit about
MTAs and anti-spam measures... and as I run the next generation of
sendmail on my system I won't use some external "smart host".)

Last I tested the IP address wasn't in any "well-known" DNSBL.

You didn't list my name :-)

See above, this doesn't apply to my system.

Anyway, Matt may block whatever he likes, it's his system.  Hopefully
he won't ask sendmail.org a question however, because he would block
my reply...



PS: my original mail was a "request" to explain TLS on the release
page (to avoid the confusion about those TLAs :-).
