However, when I test with egrep for a (positive) match with these
patterns, then they do match.
$ cat test_patterns
^(Subject|From):.*sunglas
^(Subject|From):.*Sunglasses
^(Subject|From):.*Oakley
^(Subject|From):.*Ray*Ban
^(Subject|From):.*?utf-
$ egrep -i -f test_patterns rayban.mail

Is rayban.mail a valid email message, and do these lines occur in its
header? By default procmail recipe conditions only search the header,
the body is ignored. This can be changed with the B flag.
Since grep -f searches for _any_ of the patterns in the file, it would
help running it with one pattern at a time, so you know which one
actually matched. As it is you don't know.
Lastly, some of the patterns probably don't do quite what you want. ?
is an extended regexp metacharacter, and Ray*Ban matches RaBan but not
RayxxxBan.
