For
example:
"dechost::user"@relay
For delivery agents that do not correctly understand them, the F=s delivery agent flag
causes sendmail to strip all quotation marks from the address before handing it to the
delivery agent:
dechost::user@relay
The local delivery agent should always have the F=s delivery agent flag specified. The prog
delivery agent commonly has the F=s delivery agent flag specified. The uucp delivery agent
might or might not require that delivery agent flag, depending on the specifics of the
program specified in the P= delivery agent equate. The [IPC] delivery agents should never
specify the F=s delivery agent flag.
The F=s flag also causes all leading backslash characters to be stripped from the user
part of the address.
"\\\user"@relayhost becomes user@relayhost

Note that when a lighter touch is needed, you may use F=B flag (?§20.8.18 on page 768),
which just removes all leading backslashes. For example:
"\\\user"@relayhost with F=B becomes "user"@relayhost

There are three major ways in which sendmail can be run:* as a set-user-id root process (that
is, withth e permissions of root regardless of who runs it), as a root process because it was
run by root, or as an ordinary process run by an ordinary (nonprivileged) user.
