That looks like a problem with your certificates.
You can check/verify them by openssl command.

Not sure about the postfix but for sure you can use "haproxy".
It might be more easy to maintain it then.

m not sure if there is a way to block it? Or I'm
missing something?

Just telnet on any host on 25 port and type From: some_real_email and email
will be send. I think thats how scam works.

Hi All,
I noticed that it's really easy to send an e-mail as a real user by simply
typing in the mail body:
From:
Is there any way to prevent from this? I checked that even when we specify
MAIL FROM:
and then in the body:
From:
postfix will send an e-mail with From: , the one from the body.
You can also log in to the chroot environment and do try
to execute some commands like telnet, mtr to see if
networking is working as expected.

Ok, now it's starting to be much clear.
Really appreciate your help and time!

It's of course not a production code. I'm only trying to
learn and understand how exactly it works.
I cannot find anything about "--" in the postfix documentation
(or I'm looking on the wrong page?). There is any explanation
somewhere? (instead of at the source code).
Thanks for your help!
2016-
I think I can do the same in Ruby using IO.popen like:
IO.popen(["/usr/sbin/sendmail", "-G", "-i", my_str], "w") do |pipe|
as I see in this case I don't even need to use my_str with \" \".
But I'm still confused about -f option in master.cf, and characters "--"
between ${sender} and ${recipien
Good point. I changed it to:
IO.popen("/usr/sbin/sendmail -G -i \"#{my_str}\"", "w") do |pipe|
So now it should be secure (same as using $@ instead of $*).
Am I right? or I'm still missing something?
Thanks,
Pawel

Hi All,
I'm trying to understand how content_filter works. According to the
documentation I can create a simple script and use content_filter to send
an e-mail to it.
That's my config of master.cf:
proxyunix - n n - 10 pipe
flags=Rq user=filter null_sender=
Maybe setting up:
your domain
* discard:
in your transport will do something similar? I'm not really sure what's you
plan for that. Why you need to do it?

You can also use your own script to deal with it (for example using
content_filter).
But I agree with Peter. That doesn't sound like a good idea at all so the
best
might be to understand client. Why he want's something like this.

In nowadays I would say that it's probably better to go for Ansible/Pupper
postfix module to manage it.

Hi All,
I'm having a problem when an e-mail has BCC. The problem is that I don't
see anything at my logs in my script, or in strace. It's somehow missing.
I'm sure that postfix (pipe) is calling my script since I have at the logs:
Mar 4 22:52:08 mailtest postfix/qmgr[16324]: EA9ACC794C:
from=, s
17 matches
Mail list logo
