The -d13.1 (a.k.a. -d13)
debugging switch causes sendmail to display
information about the recipients of each mail message as it is being
delivered. The -d13.1 debugging switch tells
sendmail to print the mode of delivery and then
the recipient information:
SENDALL: mode dmode, id=qid, e_from output of printaddr( ) here (Section 16.3)
e_flags = envelope flags here
sendqueue:
output of printaddr( ) here (Section 16.3)
Here, dmode is one of the delivery modes shown
in Table 16-10. The qid is the
queue message identifier (such as g7PI04TK027759). The address of the
sender (e_from) is dumped by using the
printaddr( ) routine. Then the envelope flags
(e_flags) are dumped as described in Table 16-6. Next, information about all the recipients
(sendqueue:) is printed by using the
printaddr( ) routine.

Finally, the -d13.1 debugging switch causes
sendmail to print a message every time it splits
an envelope in two:
sendall: split orig into new
Here, orig is the original queue message
identifier for the original envelope (such as g7PKuBWE027877) and
new is the identifier for the new envelope, the
near identical clone of the first. Envelopes need to split if they
have different owners.
