1 problem. As I rent, and all the mailboxes are together in one of those brick wall letterboxes, I am not able to really do anything about it. I do think Monday was just one of those days where the rain was actually blown into the mail slot, and hence flooded it. Thankfully there was nothing important in there.
similair prob here Clarkey - everyone must have complained enough though as they sent someone to fix it.
All the did was used some metal grating bent some legs on it, and it sat in the bottom of the mailbox. That way the mail doesn't sit in the bottom of the mailbox and act like a sponge.
