You could use inotify to monitor a directory and trigger a script to
send the mail.
Here is a very simple example content of such an email file, but they
get much more complex.
To: f...@bar.com
From: b...@foo.com
Subject: example email
Hello World!
If the files are valid email files with headers you could just pipe
them to sendmail.
If the files are not valid emails with headers then you could send
them as attachments. Something like the python module envelope would
be a simple way to do this: https://pypi.org/project/envelope/
The following code (function) takes a bytesIO object and attaches it to
an email.
A warning about inotify and python, if the rate of writing new files to
a directory is too high python may not keep up to it there are events
that may be "lost". I have found it the hard way.
note: 127.0.0.1 was choosen instead of localhost because in some
circunstances -> IPv6 issues

Hi everyone! I hope all of you are doing well.
Does postfix allow for sending email by copying a file or files to
anappropriate queue directory?If so, what is the format of
thefile(s)?A reference would be very helpful if someone can point me
in the right direction.
Thanks!
