Postfix message received

Question

I am writing a web application that should receive email messages to users' internal email addresses, allow administrators to approve them, and then forward them to the appropriate external user mailbox.

I installed and configured a postfix for the message receiving task. It uses virtual email addresses and my existing database where user email addresses are stored. The local email repository is maildir and I use postfix virtual MDA.

Basically, I would like to execute a script every time a new message is received, and for which the user (the message identifier maildir will also be very useful). Then I could read the message from python code (python had a module for maildir mailboxes) and paste it into the database. I can come up with three ways to do this:

• iterate user mail and check if there are new messages, but this will be ineffective for a large number of users.
• use dbmail and then check if there are new messages in the database (it would be faster, but I would have to configure everything from scratch). In addition, existing user data tables cannot be used.
• write a wrapper around maildrop / virtual to save the message in db and in maildir, but I need a way to check if the received message was successfully and successfully saved by MDA real .

Any suggestions appreciated!

Answer 1

In response to my own question, I used postfix content_filter with the X flag set in the handset and a handler that receives the address and message manually. Since I did not need to access messages in maildir, this approach works fine for me.
