Intro :

Imperial Mail is a great mod to support ironman playstyle (no save scumming). In my playthrough I'm using Death Alternative and Frostfall which might make you end up on other part of Skyrim when you died. That's why It always important for me to save my belonging somewhere before embarking into Skyrim wilderness. Imperial Mail doing a great job for keeping my gold and allow me to send important items to my destination city. 
But one big problem is, after I send my belonging, I can't retreive it until I arrive to that destination. what if I want to change destination on mid travel? what if I am robbed, and end up too far from where my destination? Why I can't ask the postmaster (Inn Keeper) to change my parcel destination to other place?

This Mod aim to fix those problems!


Main Features : 

- Inn Storage Rental
Now you can simply rent the storage to inn to keep your important belonging, even if it's not going to be sent! the cost of rental is same with the cost to rent safe storage in Solitude Post Office (Imperial Mail Feature). And the good news, you only need to pay once and able to use any storage in other Inn! 
- Transfer Items Between Inn
You can transfer you item between inn!. Cost to move item between inn is the same with cost to send items to another inn. All Items you sent will enter thae inn storage
- Bug Fixes : Rental Countdown
In original Imperial Mail, I found that safe rental days counter is not working (please correct me if this false). I attempt to fix it, so now you will not having infinite rental duration. If your rental duration is over and you have belongings inside don't worry,  you can still grab everything at once! no extra cost.
- Bug Fixes : Unpaused Menu Support
If you're using Skyrim Souls you will have a bug when trying to send parcel, the fix for this bug also included in this mod.

Known Issue :
 
- Disconnected from Solitude Post Office Safe
Imperial Mail adding Solitude Post Office building which have rentable safe. Unfortunatelly, you can't transfer directly to this safe.. But! Solitude Post Office Master also have his own storage, where you can send, collect, or transfer from. this one is already connected to other inn!
- Items are sent directly 
I'm not sure to mark this bug or feature, this might causing immersion breaking since your items will teleported directly to the destination, either by transfer or sending parcel. I was attempt to implement simulating Items travel time, but it end up only add complexity and possible bugs in the future. And at some point, It might get annoying to wait the items..
- 24 hours rental counter
If you use mod that allow wait more than 24 hours, and you do it, rental days counter will only count 1 day. This is due how the engine handle time event, and I have no plan to fix it. 

Mods Synergies
- Container and Arrow Weight Restriction - perfect addition for this mod, add limit to container. so you won't end up storing 1 million cheese in Bannered Mare
- Death Alternative - Store your spare armor and money, to minimize the loss when robbed / captured 
- Frostfall - When you passed out because freezing, chance you will end up to other part of Skyrim, just ask inn keeper to send your items to where you are now
- Let Me Drop It - Too lazy to carry Meridia beacon ? simply send it to Dragon bridge or Solitude and forget it forever  fetch it later when you want do the quest
- Breakable Equipment System - since your equipment might break anytime, having spare armor stored in the inn is a good insurance to have.
- Encumberance mods - Although currently I'm not using any, I think it can synergize well with this mod, since you might prefer send your items rather than get am encumberance penalty
