Well it's certainly possible (plenty of mailing lists do this, as does
SpamAssassin), but it's not out-of-the-box functionality provided by qmail /
mini-qmail. Instead, you'd need to modify qmail to alter the message; you
mention that you want to do this for outgoing emails, so qmail-remote.c is
probably the most appropriate place to start - either modify this, or provide
a wrapper to it. Modifying it is likely to be easier (esp. consider blast()
function). I'd be happy to quote you for that if desired.

There are various 'error' type scenarios though: This could break message
signing - GPG / DKIM, also the risk of adding 'secure' repeatedly if a message
Subject: is seen repeatedly (e.g. replying to a message that already has the
'secure' prepend). So consider carefully based on your specific use case.

Best regards,

Andrew.

There is no qmail-remote in mini-qmail. I tried writing a wrapper for
qmail-inject but can't capture all the environment variables such as
'Subject:' to modify it before sending to qmail-queue which in mini-qmail
is qmail-qmqpc.

mini-qmail looks like a difficult approach to this particular problem, although
that may just reflect an unfamiliarity with working with its source code on my
part. In your original message you inferred that 'full' qmail was an option
for you; I suggest that may be the easier approach.

Best regards,

Andrew.

Yes, I can install the full qmail on all of the 12 servers but was
wondering if anyone can suggest a way to modify the subject before
injecting into the queue. How would I do it in the full version of qmail?
Do I need a wrapper for qmail-remote or qmail-queue?
Thanks for any help.

Thanks. I guess there is no easy way doing that with a simple wrapper then.
I was able to modify bin/mailsubj to do what I need but applications do not
call that script to send mail out.
