Filter arbitrary content

[uli42]

Feature request: My employer inserts a string into every email (something like to care check external emails for suspicious content). Naturarlly, this string will be included in any quoted reply. So I would like to a have feature to strip this string (or better: arbitrary strings) before doing the quoting using a config variable. What do you think about that?

Yeah, cool idea. If you have time, take part in hacktoberfest and work on the implementation.
