First, would you kindly look into the issue of configuring M$ Outlook to
wrap lines at aroung 76 cols.

If mail can be delivered, then you really should not worry much about
controlling this because I am sure it's already taken care of in the
configure file, somewhere in the acl_smtp_rcpt. There are some entries
there with the word "endpass". They take care of that. Mine have been
slightly modified to look like:
accept domains = +local_domains
endpass
message = NO_SUCH_USER
verify = recipient/callout
accept domains = +relay_to_domains
endpass
message = Unrouteable address.
verify = recipient/defer_ok/callout=10s/callout_defer_ok
cheers
