The requirements could mean (in descending level of complexity) a local set of rules, or not being on the spamhaus black list, or not using an undesired TLD.</div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif"><br></div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Olivier's issue of bounce messages might be appropriate ... if the recipient of the bounce messages cared at all.

[is this OT, how did this start?]<br>
<br>
I use spamassassin system-wide to increase the spam score of a message<br>
from certain TLDs to near the threshold where it's just rejected.<br>
<br>
So for example in <a href="http://local.cf" rel="noreferrer" target="_blank">local.cf</a> I add a rule like:<br>
<br>
header DOTTOP_RULE From =~ /.*\.top/i<br>
describe DOTTOP_RULE BZS 20160226<br>
score DOTTOP_RULE 2.5<br>
<br>
which means just having a .TOP TLD in the From gives it a base score<br>
of 2.5, so it wouldn't take much more, tripping some other<br>
spamassassin rules, to just get it blocked entirely.<br>
<br>
But it means in theory a very non-spammy msg from that TLD might still<br>
get through.<br>
