One more time.... Yahoo is part of a consortium that is trying to adopt a new email security procedure. Some other companies are too. That new security procedure rejects mail from most mailing lists, treating it as a forgery/spam. (Wanna know why? Look up DMARC and Yahoo.) Yahoo turned on that feature last week: many web sites are now treating emails from those mailing lists as SPAM, marking the mailing list as SPAM. This happens whenever a person with a Yahoo mailing address posts to that list. Yahoo thinks it can drag the Internet into their new security procedure. I suggest that people now pretty much HAVE to dump Yahoo email addresses instead. Because most mailing lists are turning Yahoo addresses into "readers only". I think Yahoo gambled and messed up.

Due to Yahoo's DMARC policy: listserv.unl.edu lists do not accept incoming email from Yahoo.com
