-d12.1
Show mapping of relative host Debug command-line switch
In the SMTP RCPT command, sendmail is required to express the recipient’s address relative to the local host. For domain addresses, this simply means that the address should be RFC2821-compliant.
The -d12.1
(a.k.a.
-d12
) debugging
switch causes sendmail to print
the address as it appeared before it was made
relative:
remotename(addr)
If the addr is for the sender or
recipient and is being processed from a queue file,
nothing more is printed, and the
addr is processed by canonify
rule set 3. If
the delivery agent for the recipient has the
F=C
flag set
(F=C on page 768) and
the recipient address lacks a domain part, the
domain of the sender is appended, and the result is
processed by the canonify
rule set 3 again.
Sender/recipient-specific rule sets are then applied
(1
and S=
for the sender, or
2
and R=
for the recipient).
Next, the final
rule set 4 is applied, and any
sendmail macros in the result
are expanded. Finally, the fully qualified and
relative address is printed as:
remotename => `addr'
