PMG 7.2-1 Incoming emails are blocked

[chicha2k]

Help me solve the problem or point out where to look. Incoming letters from a certain address are blocked. The tracking center log shows that the letter is blocked according to the "Blackliist" rule. However, the sender's address and domain are not on the black list. Regular expressions for the domain and email address have been added to the white list.

The mail is blocked in your configured rules - more concretely by the rule called Blacklist - take a look there.

Just to have mentioned it explicitly: PMG 7.2 is EOL since over one year now - please consider updating to the latest version as soon as possible.
