Keeping this in view, what happens to mail when mailbox is full?
If your mailbox is full, it is unable to accept new emails. When a new email arrives which can't be instantly delivered because your mailbox is full we queue it and retry to deliver the email every 15 minutes for 2 hours. During this time you can free some space and your emails we be delivered.
One may also ask, does the post office deliver mail to broken mailbox? If not, they May/ Can return the mail as undeliverable. The Post Office will hold the mail but after that 2 weeks time has elapsed and the box is still unserviceable they May/Can return it to sender as Undeliverable.
In respect to this, can you leave mail in your mailbox?
You will have to leave outgoing mail in the designated slot next to the mailboxes. For those who live in a house, there is a separate mailbox for each house, mostly unlocked. You put outgoing mail in the same mailbox in which you receive mail.
What happens if mail doesn't fit in mailbox?
Not All Mail Can Be Delivered If a piece of mail is too large to fit in your personal mailbox, a carrier can leave the package at your front door or in a lobby area. If a USPS carrier attempts to deliver a package and it won't fit in the PO box, she will retain the package at a post office until you pick it up.
