|

| NOTES |
- Starting with sendmail 8.14, spaces after the colon in a header
field are preserved if requested using the flag
SMFIP_HDR_LEADSPC.
That is, the header
From: sender <f@example.com>
To: user <t@example.com>
Subject:no
will be sent to a milter as
"From", " sender <f@example.com>"
"To", " user <t@example.com>"
"Subject", "no"
while previously
(or without the flag
SMFIP_HDR_LEADSPC)
it was:
"From", "sender <f@example.com>"
"To", "user <t@example.com>"
"Subject", "no"
- Later filters will see header changes/additions made by earlier ones.
- For much more detail about header format, please see
RFC 822
and
RFC 2822
