Name
-d8.7
Synopsis
The -d8.7 debugging switch causes
sendmail to print a yes or no response to each
of the “trying” line printed by
-8.5. Yes means that the host
could successfully be fully canonicalized. A yes answer prints just
this:
YES
If the host could not be canonicalized, a more complex answer is printed:
NO: errno=errornum, h_errno=herrornum
The errornum is the system error number (if any) from <errno.h>, and herrornum is the resolver-specific error from <netdb.h>, as shown in Table 16-7.
