The OP showed that on two lines, but if it is, there would be leading whitespace. You want to match a whole logical header, not only a continued line. The expression should be: /^From:.=\?GB2312\?B\?/ REJECT GB2312 in headers Or, remove the anchor: /=\?GB2312\?B\?/ REJECT GB2312 in headers > > in header_checks.pcre, but this didn't work.

One thing the header_checks(5) manual is not clear about is how to match the line end and leading whitespace. Is it matched by a single space in the expression, or would we have to replace spaces with something like this: "[[:blank:]]+" ? -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
