Hello,

Thanks for your response.

One way to do it is to set 'staticbounceaddr' (see TUNABLES) to send the
bounces to a black-hole, rather than having Mlmmj process them. Mlmmj
will then think nothing is bouncing, so will not try to probe.

But if I do that it will disable all bounces. I want to get bounces, but I don't want mlmmj to check for bounces.
I want to do it manually.

I think removing the text/probe or text/bounce-probe list text would
also turn off the messages, but log an error to syslog when Mlmmj tries
to send one. You'd have a record of which address are bouncing that way,
though, which may or may not be a benefit.

In mlmmj 1.2.17 (debian stable version) it is not sufficient because mlmmj will fallback on /usr/share/mlmmj/text.skel/en/.
I had to remove read access to it too :

rm -vf /var/spool/mlmmj/*/text/bounce-probe
chmod o-r /usr/share/mlmmj/text.skel/*/bounce-probe

and to prevent package upgrades to reset it (ext fs only) :
chattr +i /usr/share/mlmmj/text.skel/*/bounce-probe

Is it different in mlmmj 1.2.18 ??

Beware, though, that if a lot of spam emails are being sent from your
mail server, you may end up with your IP blacklisted or something like
that. It's probably more worth your while to try to filter out the spam
and avoid it going out at all. Ignoring the problem by turning the
bounces off will just let the problem grow, unnoticed and unrestrained.

You're right. I will install a spamassassin if I find the time one day.
