Hm, I'm fetching two of them and they regularly arrive in my $work's outlook.

... wait ...

EDIT

from What XML generators are currently available on PerlMonks? # Newest Nodes :

• newest nodes xml generator (that's the base xml ticker, you need the ;xmlstyle=rss option for that, see below)

Correction

see What XML generators are currently available on PerlMonks? # RSS-Feeds

strangely I can't get outlook to tell me which one I'm using, but those look right

• Newest Nodes RSS Generator --> https://perlmonks.org/?node_id=30175;xmlstyle=rss
• Headlines, updated daily (RDF) --> http://www.perlmonks.org/headlines.rdf

the third listed ticker (external) seems to have stopped updating in 2018

updates

• GitHub Issue amended
• newest nodes has an RSS link which is just the one listed above
