iOS has been hit with another weird bug which makes clients get phantom emails from 1969 and 1970 that can't be erased. 

As some Reddit clients have found, a mistake with the mail server not downloading the headers accurately seems, by all accounts, to be bringing on some iPhone proprietors to get undeletable "invalid" messages dated back to December 31, 1969 or January 1, 1970. 

It's vague if this issue is identified with the scandalous 'January 1, 1970' bug which can block a few gadgets and that Apple has altered in the anticipated iOS 9.3 programming upgrade. We have connected with Apple requesting that they remark on the new issue and will report in the event that we get an answer. 

One analyst on Reddit clarifies that the issue presumably comes from the way iOS handles UNIX time, or Age time as it's likewise called. In UNIX time, January 1, 1970, at midnight, is the beginning time when tallying began. 

"The date of January first, 1970 just means there's no information for the date," peruses the post. "Nobody made the email malevolently, it simply has no information." 

On the off chance that the date stamp on some of your messages is set to 1970 and you can't erase these messages, have a go at crippling your Mail account in Settings → Mail, Contacts, Timetables. 

Presently leave Settings and go to Mail and the invalid messages ought to be gone. Do a reversal to Settings and re-empower your email account. This issue just appears to influence Apple's stock Mail application and when changing time zones.
