MAILATTACH
|
|
|
|
This program starts a process which listens on the LOOPBACKv4 address for
|
|
incoming connections from postfix. The postfix master should view this as an
|
|
advanced filter as explained in their documentation for post queue filtering:
|
|
|
|
http://www.postfix.org/FILTER_README.html
|
|
|
|
The original attempt was to implement this as a pre queue filter, but this
|
|
required the milter protocol and postfix currently does not implement the
|
|
replace body function from libmilter.
|
|
|
|
You can specify the following command line options:
|
|
|
|
--abort-pgp --noabort-pgp
|
|
To either abort the attachment process if PGP encryption or signatures
|
|
have been detected or not. If true, the mail will not be modified.
|
|
|
|
--abort-dkim --noabort-dkim
|
|
To either abort the attachment process if DKIM signatures have been
|
|
detected or not. If true, the mail will not be modified.
|
|
|
|
--in-port -i
|
|
The incoming smtp port/the port from which mail is received.
|
|
|
|
--out-port -o
|
|
The outgoing smtp port/the port to which mail ist passed through.
|
|
|
|
HOWTO
|
|
|
|
We essentially are MITM sniffing your email traffic and playing proxy from your
|
|
postfix to your postfix. That's how this is intended to work according to the
|
|
postfix website.
|
|
|
|
This program needs to be started via it's own systemd service on system boot.
|
|
You need to add the in and oputput ports to your postfix queue as described in
|
|
the link above. More documentation is to a TODO
