getting email bounces when people request a wiki account - sudo-sys

2 Mar 2023

it seems like every time someone requests a wiki username on
sudoroom.org/wiki, we get these bounce messages:

&lt;bullitt(a)elleko.net&gt;et>: connect to elleko.net[154.212.119.153]:25: Connection timed
out
&lt;mail(a)substack.net&gt;et>: connect to substack.net[198.51.233.1]:25: Connection timed out

so I guess there's something in the wiki config to send messages directly to
those people when someone requests an account?  And we should take those out.

but i have no idea where to begin looking for that stuff, or whether i have
permission to make changes (I do seem to have permission to approve new
account requests though)

how do I fix this?  Unfortunately I can't bring substack back, and I don't
know who bullitt is, so I guess we need to remove their emails from our
system.
