Regular Expression Examples Edited

[Petr]

Good day!
Does anyone have real examples of regular expressions for a mail handler, can you share?

Thanks a lot!

P.S. I cannot figure out why my regular expressions do not give the desired result, for example, separating the message from the rest by the desired word.

Came here looking for exactly this.

I literally HATE regex... or at least the documentation (lack of human readable documentation) around regex.
