Is there a way to have the presence of a specific header (or, better, a specific beginning to a header, where the later text might vary) causing quarantining by amavis. Use case is that postfix header_checks will identify a suspect mail and add the header before the mail is passed to amavis.
Example header which should lead to amavis quarantining the mail: X-Hold: mydomain.tld; Withheld by order of check_header.pcre (.world domain) I feel sure amavis is powerful enough to do this but the plethora of options, and the perl terminology, leave me baffled. Thanks for any help.
