> Good. Do you have non-anonymizing rDNS so that other people can tell that that's the truth?
It this 'x-y-z-y.uc.nombres.ttd.es' sufficient?
Ok, we cannot request to TTD to change the rDNS, however the domain, ttd.es, tell yo to write to abuse@ttd.es and/or postmaster@ttd.es if you detect spam practices.
I did it recently, and I received an ACK from them.

Ok, for this there are the open relay blacklists, no? So, I cannot understand why we was blacklisted in DULs (dial-up, since our addresses are not dial-up connections).
I think that, the solution: closing all potential open relay by closing all domestic connections to SMTP is the first step to closing freedom (or closing Internet).
The solution for avoiding the spam is to filter messages by header and/or body. I'm using procmail since three years and I block automatically 90% spam. By configuring this in MTAs you can avoid 90% spam to your users. Of course, this configuration must be optional because the filters are not perfect.
Recently, these facts demonstrated us massive blacklists may be innacurate or under abuse. During a few weeks, a lot of Spanish free software projects, such as GNOME-DB, were blacklisted in MAPS because "they are dial-ups connections". Altough we told to MAPS administrators that we have fixed IPs in DSL connections, it was neccesary a message from Telefonica, the main spanish telephony and Internet provider.
I had an interesting discussion with Sourceforge administrators about the accuracy of MAPS lists (SF is using MAPS lists so we had blocked all emails with SF users during a few weeks).
Now, I recommend not supporting MAPS lists. I think they are abusing on them.
Actually, I sign all outgoing messages with this:
Note.- This message may or may not arrive to you. This is
because a lot of non-spammer's Static IP addresses are being
listed in MAPS antispam blacklists. So, please, do not use MAPS
blacklists or a lot of mail for you would be lost.
