Some
delivery agents don't correctly understand quotation
marks in addresses. 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.
