It was all working fine this this evening when I started to get this message.

We apologize for the inconvenience.
It happened when I wanted to send an e-mail to someone.
The usual security question pops up when you try to send any new message.
Security question is not unusual, it keeps on promoting from time to time. However in this situation it always prompts for the security question which indicates that something is wrong.
And after entering the security code it shows this error.
I did a search on this problem but it seems no one has any clue on this. May be Yahoo is dumping mail. Or may be Yahoo itself is going bust. There has been rumor on this topic before that Yahoo is for sale.
The best option is to move away from the Yahoo mail and get your own e-mail in your own domain. All these free public e-mail suck.
I checked my other yahoo mail account and that seems to be fine. So it seems something went wrong with this mail account question. May be security is breached? Or may be someone tried to use this e-mail id to spam and yahoo put a restriction on this account.
You can try some of the following solutions
1) Clean cache and retry
2) Change password
There might have been a security breach in your yahoo account. So the first thing to do is to change the password. Neext clean cache and retry sending e-mail.
If none of above works and you still can’t’ sent message then next thing to do is to export all your yahoo contacts and keep it safe.
At the moment I’m trying to export contacts and it is in progress or may be it doesn’t work either. It doesn’t prompt with any error but it doesn’t download either. It freezes in Chrome and Firefox.
