"If you don't upgrade our mailbox, you will not receive more emails frequently
   Your mail will be closed
   Your important emails Inbox, Draft and Sent will be wiped away.

I do have 4544 messages on my mailbox! I use it like a filing cabinet. The warning I've received is from: no-reply@emailadministrator.com It has several spelling and grammatical errors, and it says: "Your mailbox is running out of data storage and it might be closed soon, Kindly add more MB to your mailbox." I am suspicious, as it's encouraging me to "Upgrade now" on a click box. Then it says: "If you don't upgrade our mailbox, you will not receive more emails frequently Your mail will be closed Your important emails ''Inbox, Draft and Sent'' will be wiped away. Note: Upgrade is free of charge, You will not be charged for the upgrade. © 2015 Email Administrator. All Rights Reversed." Has anyone had a similar message? If it's spam, I just delete it . . . If it's not, how do I add more MB to my mailbox? I can't seem to find an answer to this specific question. Many thanks Idunno
