Hi, at first thanks for the great tutorials on this page! I'm having the following problem: I started with "The Perfect Setup - Debian Etch", then "Integrating amavisd-new into Postfix For Spam- and Virus-Scanning", i did not took every single step (like DNS-server, Quota) but now all seems to work quite well. I can send and receive mails via Mailclient and installed "Horde Groupware Webmail Edition" for webmailing. So all in all, everything works fine...unfortunately, some mails are delivered twice or even 3 times. They are exactly the same (same header,same ID). This happens only sometimes, i am not able to reproduce that error. I found out that this seems only to happen when there are more than 1 recipient, all doubled mails have a minimum of 2 or 3 recipients. So i googled around and found some information - it seems to be a problem with postfix and amavisd and virtual aliases that are used....obviously, postfix tries to rewrite addresses before and after contentfiltering and that - sometimes - results in duplicate messages. So i found this option "-o receive_override_options=no_address_mappings" and added it to master.cf but it doesn't seem to help Does anyone suffer the same problem? Here my master.cf: Code: # # Postfix master process configuration file.
