Hi,

Can anyone point me in a direction to start creating my own custom
cleanfeed rules?

I'd like to translate what -- I think -- is a simple filter in
Thunderbird to be a cleanfeed rule to reject posts at thee server.

subject contains "blank"
subject contains "card"
subject doesn't start with "re"
from contains "@gmail.com"

I'm also okay if the "doesn't start with" is a less precise "doesn't
contain".

Thank you for any pointers you can offer.

In cleanfeed.local

Into the function local_filter_last

subject contains "blank"
subject contains "card"
subject doesn't start with "re"
from contains "@gmail.com"

if ($hdr{From} =~ /\@gmail/) {
if (not $hdr{Subject} =~ /^re/i) {
if ( $hdr{Subject} =~ /card/i) {
if ( $hdr{Subject} =~ /card/i) {
return reject( 'Bad post!');
}

}
}
};

I'm also okay if the "doesn't start with" is a less precise "doesn't contain".

Thank you for any pointers you can offer.

I'm sure that someone will give a two or three lines solution...

Thank you for that example.

I believe I understand it well enough to make the following bug report.

It looks like you're checking if the Subject header contains a case
insensitive "card" string twice. I suspect you copy and pasted lines
and meant to change one of them to "blank". ;-)

I believe I will be able to take your good example and add it to my cleanfeed.local file.

I'm sure that someone will give a two or three lines solution...

I could be ornery and say that there's no possible way to do that,
thereby guaranteeing that multiple people will prove me wrong. }:-)

Thank you again Stéphane. :-)

Yes, it's a big source of bugs...


Maybe you can simplify the two copied pasted rules by this one :

if ( $hdr{Subject} =~ /blank.{0,50}card|card.{0,50}blank/i) {

I believe I will be able to take your good example and add it to my cleanfeed.local file.

Local rules work well!

I probably could.

I use regular expressions extensively. But I've learned that it's
better for me if I try to avoid over optimizing REs. Instead, my
ability to maintain them long term is greatly enhanced if I keep them as
a set of multiple simpler REs rather than a single more complex RE.
Maybe that's just me.

Local rules work well!

I look forward to trying it out as soon as I find a spare Round-Tuit.
