Nigerian Railway Corporation recruitment mailbox is full!

Okay so when you try to apply via the email address ([email protected]) provided by the Nigerian Railway Corporation for their ongoing recruitment exercise you get a mailbox full error message.
A lot of applicants have been receiving the following messages after sending their application to [email protected]

Delivery has failed to these recipients or groups:
[email protected] ([email protected])
The recipient's mailbox is full and can't accept messages now. Please try resending this message later, or contact the recipient directly.


This simply means that the email quota for [email protected] is full. Apparently the allocated quota for this email address isn't large enough to catch applications from thousands (or possibly millions) of job seekers in Nigeria. Email quotas work in such a way that once the limit in size is reached, the mailbox would be deemed full and will not be able to receive emails. 
However, there is an option for unlimited storage and that's what I thought they should have used.

I'm really amazed and disappointed that a Federal Government body such as The Nigerian Railway Corporation couldn't  prepare well for this exercise and no official statement or correction has been made with regards to this. Jobzilla has tried to reach them for an alternative email address, but we have not gotten any response from them yet.
