Blocking Mail with specific alias part in from

[GKrem]

Hello,

i want to block all emails from

"Dr. med. Frank" <info@happynonsense.com>

where the part between < .... > can be anything.

So i wrote a regex in the global blacklist looking like this:

^\"Dr\.\smed\.\sFrank\"

As far as i could test with regex101.com the expression should be exact what i want.

But if i test it in proxmox i get the result that the expression is not matching.

I wonder if my expression is wrong or if the test function in proxmox is giving me a wrong result?

Any help with this issue?

Thx in advance.

Quickly tested this on a test-installation of mine - works here (copy+pasted your regular expression and the test-string)

* Which Version are you running? (`pmgversion -v`)

Keep in mind that Who Objects match the SMTP-envelope sender and not the 'To' Header (see e.g. [0] for a quick explanation).
If you want to match the To header you need a 'Match Field' What Object

I hope this helps!

Hello Stoiko,

proxmox-mailgateway: 6.4-1 (API: 6.4-4/1c8a73c7, running kernel: 5.4.114-1-pve)
pmg-api: 6.4-4
pmg-gui: 2.4-3

i want to check for incoming mails - field "from". Guess i should be right with the "Who-Object" than?

Here's what i see in web browser:





Maybe i just wait and see, as this spam is comming often.

Thank you for you time and prof. answer.

Have a good day and stay safe.

sorry for the mistake w.r.t. from/to but the point with Envelope sender vs From header remains.

Check the error-message - the anchors are added by PMG - try dropping the '^' in the beginning, and add '.*' in the end

I hope this helps!

Yepp - this made it work. Allthough i am still not sure if my regex was wrong or just the routine to test.

Again - Thx...

Actually both - your regex was not wrong, but since PMG automatically anchors them (sets '^' in front and '$' in back) - it would not have matched.
The test routine correctly said that the regex does not match.

I guess we should mention this in the documentation - but for now - trust the test-routine - if it does not match then PMG will not match.
