Hi Wietse,

I do not know if skipping the printable() call does have any side-effects

As a short-term fix it is probably OK, because the cleanup daemon
already filters the response. But smtpd should not rely on the
cleanup server doing that.
Right. That seems sensible.
A longer-term solution should enforce the single-line form (with
the existing printable(foo, ' ') call) by default, and allow
properly-formatted SMTP when SMTP is allowed. This way, proper
operation of the SMTP daemon won't be affected when the cleanup
daemon is borked. This is basic error containment.
3.5 then. :-) Right now I am still on 3.2 but this gives me a good reason
to upgrade.
In the meantime, thank you for the workaround.
cheers,
Anreas
