Dear Bungie / Children of Zsakos Ember,
[b]PLEASE have the Tower postmaster post a notice that "ONLY X NUMBER OF ITEMS WILL BE HELD FOR YOU HERE !" 
...AND THE REST WILL BE DELETED..... after X number of days....!    
Signed Kadi 55-30 [/b]
At this time it's unclear what the limit of held items is,  how long the items will be held, and when they will be deleted by Postmaster Kadi 55-30
This is a difficult time right now even with the expansion of the vault.    
I've lost several legendary items simply because these limits are not clear, were not posted, and I had to learn by losing hard won items.
< Edit > 
Perhaps Bungie could make the time limitation clearer by using a color scheme to indicate that the items are expiring on the shelf.
Green:  Item just landed ..... will be held for _____  days.
Yellow:  Item is at midpoint of time limit to be held for player.  Time / Days remaining are ______. 
Red:    Item to be deleted by ______ pm today. 
Once max items limit is reached: a notice is posted for viewing by player upon interacting with the postmaster. 
( example ) 
[b][u]RED LETTER NOTICE FROM POSTMASTER[/u]: [/b]  "You have reached your lost items limit !    No more items may be recovered here until you delete X number of items.    Only _____ number of items can be held at any time by the Postmaster."
