Hello,

Standard delimiter for signature is "-- " (dash dash space).
See http://email.about.com/od/emailsignaturenetiquette/qt/Use_the_Standard_Email_Signature_Delimiter.htm

It would be very cool, if you could automatically remove the signature when receiving task by e-mail (exactly like "-end-").

I know I could use "-end-", but it's not standard, and I have to add it by hand, where "-- " is automatically added by my mailer.
