- I had written a specific procmail rule a while ago,
- it had worked for quite a while,
- for quite some while now it had not worked as expected;
- I had a look at the header lines as displayed by my e-mail reader,
- I also had a look at my procmail LOGFILE;
- the subject line looked rather differently,
- all the blanks were rather ‘_’, i.e. underscore characters, that’s because the subject wasn’t in 7-bit ASCII but rather in UTF-8;
- for readability I now match this by the ‘.’ wild card, I think, that’s good enough.
