This is a bad idea. Emacs should set the envelope address only on
specific request from the user. Provide an easily customized option,
yes. Default, no. The default is to let the MTA figure it out.
Users who change the From address had better know what they are doing.

Don't you have this backward? The envelope address is set by the MTA,
which defaults to using the mailbox of the logged-in user. This
corresponds to user-mail-address because user-mail-address defaults to
the same value. (I don't know or care what smtpmail.el currently
does, but here it is functioning as an MTA.)
Note that on some systems unprivileged users using the system MTA may
not be able to set the envelope address at all.

A mail message must have a From field to conform to RFC 5322 (see
table on p. 20 of that RFC).
