Postfix update generic.db

How the hell am I supposed to remember the address for this blog next time I forget the same command? Some 5th or 6th googleing led me here. But thanks anyway. At least you helped me this time.

Despite the difference, Postfix lists are described here because they use the same underlying infrastructure as Postfix lookup tables. You can save yourself a lot of time by implementing Postfix first with local files such as Berkeley DB.

Local files have few surprises, and are easy to debug with the postmap 1 command:. When you do this, you should use the postmap 1 command again, to verify that database lookups still produce the exact same results as local file lookup:. When you make changes to a database while the mail system is running, it would be desirable if Postfix avoids reading information while that information is being changed.

It would also be nice if you can change a database without having to execute "postfix reload", in order to force Postfix to use the new information. Each time you do "postfix reload" Postfix loses a lot of performance. If you change a regexp :, pcre :, cidr : or texthash : file then Postfix may not pick up the file changes immediately. This is because a Postfix process reads the entire file into memory once and never examines the file again. If the file is used by a short-running process such as smtpd 8 , cleanup 8 or local 8 , there is no need to execute "postfix reload" after making a change.

If the file is being used by a long-running process such as trivial-rewrite 8 on a busy server it may be necessary to execute "postfix reload".
