Is it possible to programmatically 'clean' emails?

Question

Does anyone have any suggestions as to how I can clean the body of incoming emails? I want to strip out disclaimers, images and maybe any previous email text that may be als

Answer 1

In email, there is couple of agreed markings that mean something you wish to strip. You can look for these lines using regular expressions. I doubt you can't really well "sanitize" your emails, but some things you can look for:

1. Line starting with "> " (greater than then whitespace) marks a quote
2. Line with "-- " (two hyphens then whitespace then linefeed) marks the beginning of a signature, see Signature block on Wikipedia
3. Multipart messages, boundaries start with --, beyond that you need to do some searching to separate the message body parts from unwanted parts (like base64 images)

As for an actual C# implementation, I leave that for you or other SOers.
