Re: warning messages

Hello from your friendly IDM list admin,

The mailing list manager we use, Ezmlm, is extremely cautious about 
dealing with bounce messages. If it sees even just one failed message (and 
messages sporadically fail with depressing regularity, particularly 
sending to gmail), it'll send you directly a "probe" a few days later, 
which will send you details about the bounce it's seeing. If that probe 
*also* fails, then it will remove the address. But if it succeeds - which 
is the warning message you're seeing - then you won't be removed. However 
that warning message also likely contains details about why the bounce 
happened - what the message was back from the server it tried to send to, 
for instance, or if there was a local issue on hyperreal, which there 
hasn't been, to my knowledge.

So if you're concerned, feel free to send me the bounce warning / probe 
message you get, and I can try to figure out if gmail (and it's always 
gmail) is bouncing these messages for something I can try to do something 
about, such as being put on a spam blacklist. I don't get informed when 
those kinds of warnings get sent because they're so frequent. But usually 
the underlying causes of sporadic issues are things I have no control 
over.

For the more nerdly of you out there, Gmail is threatening to block all 
mailing list emails in the future that don't use a generic "From" header 
that matches the domain of the sending MTA based on DMARC rules. For 
example, that means senders who use a @gmail.com address, but email to 
[email protected], when that message comes back to Gmail they will block 
it on the premise it looks like spam, despite that being how email 
forwarding and email mailing lists have worked since day zero, and will 
break email replies and otherwise make it challenging to know who sent an 
email. I have no time/interest in modifying ezmlm to forge the From 
headers to a generic address, as some other mailing list providers have 
done, so if that happens and gmail was no longer accepting mailing list 
emails from @hyperreal.org because of it, I'll probably just move all 
these to groups.io and get out of the mailing list hosting hobby.

Also btw if you want reliable email from mailing lists or non-gmail 
senders, don't use gmail.
