Hi Cannon,

Yes this was a change I implemented earlier this week when I upgraded the 
mailing list software to resolve an issue with respect to DMARC policies.

I may be able to get the original "From" to show up again for everyone except 
for those sending from a domain with a DMARC policy set to reject (such as 
aol.com and yahoo.com), those domains are the precise reason it was changed. 
Without the change it would cause messages we relay for those domains (aol.com 
and yahoo.com) to have the delivery rejected by other domains like gmail.com 
which causes a cascading effect where the mailing list server processes the 
bounce back from the gmail.com addresses and then disables mail delivery for 
the subscriber thinking there is an issue with the gmail account, when really 
the issue is that the message was relayed when the dmarc policy is set to 
reject so gmail properly rejected it as per the dmarc rule.

The new behavior you see is called munging the address, and it is the nicer 
alternative to rejecting all messages from aol.com and yahoo.com - I just 
applied to everyone when I may not have needed to, I have relaxed the setting 
back and it should now only "munge from" for anyone who posts to the list from 
a domain with a DMARC reject/quarantine policy.

Although if I continue to see bounces due to relaying messages for other 
domains I may need to re-enable it for everyone.

Kind Regards,

Tim PENNER
