I have a working SMTP setup in Postfix
transport_maps = hash:/etc/postfix/transport
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
All is good with the SMTP, however now Postfix ignores the header_checks
header_checks = pcre:/etc/postfix/header_checks
or
smtp_header_checks = pcre:/etc/postfix/header_checks
Is there a priority of operations, like "use transport and stop"?
If yes, what could be a way to apply header_checks before transport?
Thank you!
I am not 100% sure why, but when I changed transport map from *:
* relay:[THE_SMTP_HOST]:587
to
specific_email#domain.tld relay:[THE_SMTP_HOST]:587
another_email#domain.tld relay:[THE_SMTP_HOST]:587
the header_checks started working.
(I tried .domain.tld - SMTP stopped working at all)

According to this document: https://developer.chrome.com/blog/private-network-access-preflight/#preflight-requests. Chrome should enable preflight Private Network Access request since chrome 98. It seems that it was working correctly and I did a setup my configuration to this new feature.
But now in versions from this page (99, 100, 101): https://www.chromium.org/getting-involved/dev-channel/ in network console I am observing only regular requests in network console. Could someone please explain this?
Thanks!
I found information, that it has been rolled back for now.

when our website was infected，we always just change the root password and the mysql password，fix the code where have vulnerability。But I think it is not enough ， does anyone have more advance on it？ I just have no idea that whether he has the backdoor in our system or have other attack that I haven't know about。
The problem is, that after the system was once hacked, you cannot be 100% sure that the hacker did not leave you a backdoor, unless he left a log of what he did.
The best way would be complete reset the system. Re-install the OS and completely rebuild the server. However that might not always be an option.
I would advise you to
Rebuild the system
Check all code using sql in you app to use prepared statements
log the sql for some time and go through it, to see if the hacker tries again and make double sure you get the code he aims at
(original post spoke of injection - not infection)
