Nice to see a deviation in the topic of the thread. First of all, congratulations on your compilation of these information about the Postal industry of Sri Lanka; ofcourse it contains a cultural + historic element over the fundamental objective of Post.
Well, I should say, the Postal industry in SL is alright, does well, VERY CHEAP, accessible, and it tends to be vivid, but there are certain downfalls, especially when it comes to overseas parcels coming into Sri Lanka, tends to get misplaced, damaged, stolen/lost, and can be unreliable, I've had personal bitter experiences with relation to this. This ought to be eliviated + the postal scheme should be made friendly to incoming parcels + courier etc. from abroad; but part of this change should be attributed to the Customs department definitely.
I suggest an online tracking system for parcels sent out of SL and incoming, but all these advancements must not damage the cultural and historic beauty of SL's postal industry.
Good post, Perera.
