Spanish Internet Provider's SMTP traffic Blocked

      While there are sometimes reasons to delay blacklist checks, the best (and probably the most common) current practice is to reject immeadiately, during the SMTP transaction, with a perminant failure code (usually 550). This failure message can be customized in most modern SMTP daemons, and on many SMTP daemons, its trivial to include TXT records from a DNS blacklist in such a custom message automatically.

      In a configuration like this, the sender gets something like the following:

      Your message could not be delivered because one or more recipients were rejected by the server.
      550-Access restricted - Your host is currently blacklisted at:

      Such a message is not only informative to end users, but it also encourages senders of legitimate mail to make contact with an address that's been made exempt from filtering (mail to postmaster shouldn't be filtered, except in a denial of service situation, per various RFCs.)

      Blocking later and sending bounces, or silently deleting (at least at the provider level) actually causes more problems than its worth - spammers will forge, so if you bounce later, you bounce to the wrong person, creating MORE spam, and silently deleting makes legitimate customers upset when mail doesn't go through, and makes troubleshooting missing mail very difficult.

From my head I would say 50% of the market share is on Telefonica hands, but isn't the whole country. Still is a nice way to make up a headline for /. ;)
