H_RECEIPTTO Header Flag (V8.7 and Later)
Some headers contain information about to whom a
return receipt should be sent. Return notification
is triggered by the NOTIFY=SUCCESS extension to the
RCPT To:
command. If the PrivacyOptions option’s noreceipts (PrivacyOptions=noreceipts on
page 1068) keyword is specified, no success return
notification will be sent. Beginning with V8.10, if
the RrtImpliesDsn
option is set, the presence of any header with
H_RECEIPTTO set will cause
sendmail to act as though
NOTIFY=SUCCESS
was specified, even if it was not.
Prior to V8.10, no headers had this flag set. For
V8.10 through V8.12, the only header with this flag
set is the Return-Receipt-to: header (Return-Receipt-To: on page 1165).
Beginning with V8.13, the Delivery-Receipt-To: header (Return-Receipt-To: on page 1165)
also has this flag set.
