== Email problems with yahoo == 

 My reply to you was erased. There is a known problem with emails: for almost a year now, emails have been bouncing if the sender's email address is @yahoo.com, see phab:T66795, Wikipedia:Village pump (technical)/Archive 129#Is "Email this user" on the blink? and the threads linked back from there. This often comes up at VPT, and some people are under the misapprehension that the recipient's email address is the problem - it's not, it's that of the sender.
