This seems like it should be an easy thing to do…
I populate omnifocus extensively from my exchange server email client outlook via the omnifocus email address method.
However, this results in my email signature being included in all the notes of my omnifocus tasks and making it all very messy.
Is there a way to search for a multiline text string (i.e. the email signature) and replace it with 0 characters (i.e. deleting it)
specify the signature file text in the omnifocus settings and this text is eliminated from the database in the background or during cleanup.
I went to go file your enhancement request and found some evidence that if the signature is separated from the mail body by "-- " (dash dash space at the beginning of a line), we strip it automatically already. Does that work for you?
