Is it possible to use regular expressions when creating an email filter?

Posted

I want to move to the folder all the letters for which the header has a certain format. For example:

The regular expression for these headers will be:

  • \[(.*)\](.*)
  • \[(.*)(example\.com|example\.net)\](.*)

The second option will exclude the movement of some letters that do not match the regular expression.

For example: * [promo.example.com] My first message * [example.com] My second message * [foo.example.net] Third message * [bar.foo.com] Foo bar baz The regular expression for these headers will be: * \[(.*)\](.*) * \[(.*)(example\.com|example\.net)\](.*) The second option will exclude the movement of some letters that do not match the regular expression.

  • \[(.*)\](.*)
  • \[(.*)(example\.com|example\.net)\](.*)

The FiltaQuilla add-on (for TB 60 and lower) allows regex for searches, but not for filter actions. I'm not aware of any way to apply regex to message filters in TB 68. See if you can accomplish the same result using e.g. From contains example.com, or possibly create filters for custom headers.
