Synopsis
Ordinarily, V8
sendmail forces envelope-sender route
addresses[28] to be enclosed in
angle brackets. But beginning with V8.7
sendmail, angle brackets can be omitted by
specifying F=d.
Under some circumstances it is possible for these angle-bracketed
addresses to be given to a shell, causing them to be wrongly viewed
as I/O redirection. This problem is most common with the UUCP and
prog delivery agents.
[28] Also see the
DontPruneRoutes option in DontPruneRoutes, and how route addresses are handled in rules
in Section 19.3.3.
