I note previous correspondence saying this had been corrected. I am using the latest version of Usenapp, 1.27.2, in os x 14.3 Sonoma. Whether I just include the text of my signature or my own correct delimiter the space after the two dashes is omitted in the message I compose and in the published message when I post it. It may or not be relevant but if I attempt to include a blank line between the delimiter and the signature text, or if I start with a blank line in the signature composition box this is stripped off too.
Many thanks for your advice,
