Re: Mailing-lists, failing probes, unsubscriptions

This kind of mass unsubscription is often due to DMARC.


 Ah, thanks. Time for me to understand how DMARC works, then, and make
ezmlm work with it.
 Sigh. E-mail gets more and more broken every year; soon it will just
become impossible to run a list.

This kind of mass unsubscription is often due to DMARC.

please see:

   https://wiki.list.org/DEV/DMARC

for a description of how the mailman folks describe the problem and how
they deal with it.

I think the skarnet lists are probably running ezmlm, i don't know that
toolchain well enough to suggest a way to resolve the issue.

Mailing-lists, failing probes, unsubscriptions

2017-11-30 Thread Laurent Bercot


 Hello,
 The skarnet.org mailing-lists use a probing system to automatically
unsubscribe addresses that don't work anymore. When an address fails
3 consecutive times, it gets removed.

 In the past year, or sometimes at an older time than that, a lot of
addresses have apparently failed enough probes and been unsubscribed,
even still working addresses. Only today was it brought to my
attention.

 I have manually resubscribed all addresses that got removed because
of a probe. If they keep failing, either they don't work and their
being removed again won't be a problem, or there's something more
serious going on and I'll have to investigate what's happening.
If you don't want to be on the mailing-lists anymore, please
unsubscribe manually.

 Sorry for the inconvenience.
