smtp.mail.yahoo.com without SSL?

[St]

Hello,

Got two question:

1.) I've got an alarm device that automaically used to sent emails to my email address via smtp.mail.yahoo.com port 25.
This has worked until well into December last year (2013).
It now doeasn't work anymore. Settings have remained unchanged (user name, PW etc...).

Error is "Failed to authenticate to smtp.mail.yahoo.com"
When using port 587, it returns the same error.

All other ports need SSL/TLS but the device doesn't support any of these unfortunately (which in this case isn't really necessary).

Does anyone know where the problem could be?


2.) Was looking for an easy to find link to contact Yahoo directly. But where is it? CustServ is only on Facebook and Twitter. How awkward....
Does anyone know the link?
