Hello Boyan,

BA> Thank you for the tip, I also use postfix. I am not familiar with

Ah, you haven't got Postfix checking your dbmail.aliases database to
see if the users exist yet... So Postfix doesn't know to bounce
non-existant users before the message is collected.

Are you using dbmail with MySQL or Postgres? If MySQL, you need to add
the following line to your main.cf file:

local_recipient_maps = mysql:/etc/postfix/mailbox.cf

where mailbox.cf contains the parameters for checking an address
against the dbmail aliases table, such as:

user = postfix
password = password
dbname = dbmail
table = aliases
hosts = 192.168.2.2
select_field = alias
where_field = alias

Reload postfix, and dbmail will no longer see messages for
non-existant users, so you'll not get those dbmail-generated bounce
messages.

The Postfix-generated messages are controled by:

# what to tell postmaster about
notify_classes= resource
                software
                policy
                protocol
                2bounce
                bounce
