Nope, that statistics I have are probably from looking at many
thousands of domains, which have probably been >90% (maybe >95%) spammers.
I said someone else might have some reasons that didn't occur to
me: I have seen cases and can even understand using wildcard 'A' for
subdomains. Just curious, but why do you do it - clearly, by even responding
you must have a valid reason and are *very* unlikely to be a spammer. I do
notice that you lack any valid 'A' or 'MX' records for some of the bare
domains; I don't have an 'A' record for mine - but to keep on the "good"
side of the RFCs, I do have a (actually many) 'MX' records for my bare
domain(s). Also, just curious, but do you have problems with the forward
and reverse DNS of you mail servers not mapping together (ex. mail.dailykos.com
maps to 69.9.164.210, but the reverse of 69.9.164.210 is faye.voxel.net - in
particular do you have problems with ISPs like AOL?). Also, I'm not sure
if my own servers would accept mail from a host like that - It would depend
on the HELO/EHLO argument you used. Would you try and send a test message to
plectere.com from that machine? I'd like to know if I would or wouldn't
accept it, and if not what reason the servers would give (it would have to
be a standard Postfix option to get refused for DNS reasons); Right now I
have a single exception case where a server that talks regularly to me has
forward and reverse DNS that don't match - and they pay me, and they just
contracted out the DNS and email and are having lots of problems with many
sites refusing mail from them.
Anyway, this is an argument for keeping the score low, not against
the rule (yet). What kind of traffic do you generate (not receive, but
that is interesting also)? i.e. do you generate mail from all these domain;
I have many, but only send mail from one - if the domains don't generate
outgoing mail, it doesn't matter anyway.
The only reason that occurs to me is using virtual hosts on a web
server, and then you would probably be better suited to LDAP and traditional
DNS, just with (potentially) a lot of entries!? Looks like your "create your
own blog" might be this last case.
Please let me know,
