Comments in :include: Lists
IDA and V8 sendmail allow
comments in :include: files. Comment lines begin
with a #
character. If the # doesn’t begin the line, it is treated
as the beginning of an address, thus allowing valid
usernames that begin with a # (such as #1user) to appear first in a line by
prefixing them with a space:
# Management ← a comment frida george@wash.dc.gov # Staff ← a comment ben steve #1user ← an address
Note that because comments and empty lines are ignored by sendmail, they can be used to create attractive, well-documented mailing lists.
Under older versions of sendmail, comments can be emulated through the use of RFC-style comments:
( comment )
By surrounding the comment in parentheses, you cause
sendmail to view it (and the
parentheses) as an RFC-style comment and, thus, to
ignore it:
( Management ) frida george@wash.dc.gov ( Staff ) ben steve
This form of comment works with both the old and new sendmail programs.
