[sf-lug] (forw) Uncaught bounce notification

Mon May 2 01:15:24 PDT 2022

Hi, aaleksey at ucla.edu and other friends far and near.

Because of modern antiforgery measures rolled out in SMTP
infrastructure (SPF and DKIM/DMARC), it no longer reliable to use
/etc/aliases, ~/.forward, and similar simple mail reflectors to
redirect mail across SMTP domains.  (Those mechanisms remain useful
intra-domain.)  Subscriber aaleksey at ucla.edu's attempt to have his
sf-lug at linuxmafia.com subscription do such redirection to (some address
at) GMail was causing bounces, because it transgressed antiforgery rules.

I have therefore removed aaleksey at ucla.edu from the subscriber roster.
Ordinarily, I'd have substituted the member's end-destination address
(in this case on GMail), but cannot determine from the below-quoted
bounce what that is.

aaleksey at ucla.edu, please feel very welcome to directly subscribe
your GMail address -- or re-subscribe your ucla.edu address _without_
the forwarding to GMail.
