FWIW, during the last week this Syslinux Mailing List received emails 
from 3 different email addresses from Yahoo. Such emails did not arrive 
to my inbox (nor to any other area of my email account). I don't know 
whether there are email providers other than Hotmail (and its family) 
behaving in a similar way, but I would guess that we cannot discard 
such situation.

In other words, currently there is a chance that some members of this 
mailing list might not receive part of the emails (and they probably 
would not know it).

I also don't know whether there are email providers other than Yahoo 
that have chosen to follow current Yahoo's policy, producing similar 

I wonder (please forgive my ignorance), whether there would be any 
change/improvement if the "Reply-To:" and "CC:" fields would be 
interchanged (back) from the current behavior (since March 2014 or so, 
http://www.syslinux.org/archives/2014-March/021895.html ). Perhaps 
Hotmail (and family) would accept these (Yahoo-originated) messages 

(To be clear, just in case, the "Reply-To:" behavior in this Syslinux 
Mailing List has nothing to do with the change in Yahoo's policy. I 
just wonder whether we might see some improvement regarding some of the 
effects of the latter if the former would change back.)
