Trace header generation and skipping

Debug command-line switch

Each header line created for the bounced message is displayed with two leading spaces. For example:

 --- putheader, mailer = *file* ---   Return-Path:  you  

Then certain headers are excluded from the bounced mail message header. Those with the H_CTE flag set (Section 25.6.5) and either the MCIF_CVT8TO7 or MCIF_INMIME mci flags set will have the text:

 (skipped (content-transfer-encoding)) 

appended and that header will be skipped (excluded).

Any header that has both H_CHECK and H_ACHECK flags set and doesn't have identical delivery agent flags set for itself and its cached connection information will also be skipped:

 (skipped) 

All re-sent headers (those marked with H_RESENT) are also skipped:

 (skipped (resent)) 

Return-receipt headers are also skipped:

 (skipped (receipt)) 

If a Bcc : header (Bcc:) is being skipped, this is printed:

 (skipped -- bcc) 

Finally, valueless headers are also skipped with this message:

 (skipped -- null value) 

Any headers that survive this skipping process are included in the eventually delivered bounced message. Note that MIME headers are not generated or displayed here (-d43).
