Hello Áron, Á> Would you be so kind tell me how can I stop dbmail sending mails from Á> itself? DBmail sends hundreds of e-mail, like this:
As Daniel said, the secret is to keep the mail to bad addresses from ever reaching dbmail. There are a number of spam programs that COUNT on systems accepting email before checking that the user exists, to allow them to relay. It's one of the reasons that Exchange and GroupWise are extremely difficult to secure from relaying. If you are using Postfix as the MTA and you have compiled MySQL or Postgres support into it, you can simply have it look up local addresses in the dbmail aliases table, before accepting delivery. For MySQL, the line to add to main.cf is: local_recipient_maps = mysql:/etc/postfix/mailbox.cf and /etc/postfix/mailbox.cf contains: user = sqluser password = sqlpassword dbname = dbmail table = aliases hosts = sql.mydomain.tld select_field = alias where_field = alias Now, postfix will no longer accept undeliverable mail for your domains... so dbmail won't have to bounce it. -- Jeff Brenton President, Engineered Software Products, Inc http://espi.com Questionable web page: http://dididahdahdidit.com Liberalism grants you the freedom to advocate any idea*. * Please see http://www.dididahdahdidit.com/except.php for a current list of exceptions
