I got an error message (supposed 'suspicious activity') preventing me from sending any outgoing mail.

Fortunately this problem appeared to somehow resolve itself after around 12-18 hours over the weekend.

It’s a good thing it did, because if I had still been waiting for Yahoo to fix it, it would've taken days!

If your IT suspects ’suspicious activity’ on an account, why doesn’t a verification message get sent to the account owner (as would happen with banks etc), so that they have an option to override the problem if they know everything is OK... rather than the user being blocked from sending all outgoing emails?

This caused serious problems for me for a while, as I rely on my Yahoo Mail to conduct day-to-day business and interactions.
