|Hallo Steffen!

|Very nice to read your suggestions!!
My pleasure.
|That sleep 5 is in my own init-alert Debian package.

Ah, ok.

It does not matter which MTA is used, it always waits until that
program (may it be s-nail itself) returns.

|I do not know any other MTA, I am a Courier user since the beginning.
|So courier rewrites addresses like this domain-less one.
It is because of the <root>, this is not a valid domain. If
$DAEMON is an address by itself, how about "root <$DAEMON>" or so?
|Does -r also set the MAIL FROM: address?
Yes. It sets *from*, but that can be overwritten in addition,
too.

|I've just switch to s-nail from long-time Heirloom mailx usage.
|As the comment says: "Hack to pass from address to sendmail"
|Heirloom mailx had no option to set MAIL FROM: address.
|Is it -r in s-nail, right?
Yep.
|OK. I add -S expandargv and -S sendwait
|Thanks.
|
|All the best to you!
All in return.
Good night!
