25.12 Alphabetized Header Reference | 1161
This is hardcoded into sendmail. See the SendMimeErrors option for further details about
this header.
The MIME-Version: header should never be declared in the configuration file.
25.12.27 Posted-Date:
Date submitted sendmail
The Posted-Date: header is used by some old Usenet news software and some mailing-list
software to indicate the date and time that a mail message was posted (submitted for distribution).
The Date: header, on the other hand, shows when the message was mailed. In
actual practice, the two usually show the same date and time.
When sendmail tries to determine the originating date of a mail message, it first looks for a
Posted-Date: header. If one is found, it uses that date. Otherwise, it uses the date from the
Date: header. Whichever is used, the result is stored into the $a macro (?§21.9.2 on page
802).
The Posted-Date: header is not a part of the RFC2822 standard, so it should not be
declared in the sendmail configuration file.
25.12.28 Precedence:
Set ordering in queue sendmail
The Precedence: header, when the QueueSortOrder option (?§24.9.92 on page 1073) is
appropriately set, is used internally by sendmail to order the processing of messages in its
queue. A full description of the possible field values for this header is given in ?§25.
