sendmail signature

[Paul Sperry]

Does any one know of a way to append a "signature" to every e-mail in sendmail,
This is acutally going to be a disclaimer.
I looked through the sendmail.cf but didn't see anything.
Thanks and Happy Holidays.

Hi,

I got curious and started looking at sendmail.org. I found a FAQ that briefly discusses doing signatures. It says that you can do it, but it is hard to do and unsupported. Here is a link to the FAQ:

You could run in queue-only mode and have a cron job append the text to each df file before sweeping the queue. But with all the mime-types and stuff out there, it's hard to say what it could mess up or whether it would be visible.

If a header is acceptable, you can define one in /etc/mail/sendmail.cf like this:

Where in the sendmail.cf can you insert the header?

[W.C. Epperson]

The "H" directive could be placed anywhere in sendmail.cf before the rulesets start. In practice, I'd put it at the end of the part where the other "H" directives are. It looks something like this:
#########################
# Format of headers #
#########################

H?P?Return-Path: <$g>
HReceived: $?sfrom $s $.$?_($?s$|from $.$_)
$.by $j ($v/$Z)$?r with $r$. id $i$?u
for $u; $|;
$.$b
