Mail to alt didnt arrive

Hi I mailed 8.5k gold and a blue item but it didnt arrive

Sender: Porneliahub
Recipient: Porneliushub

Then you've made typo and your only hope is person being decent and sending it back/not claiming for 30 days.
Or your toons are from different factions. Anyway, you won't get anything from server, as it is your mistake.
P.S. stupid character names BTW...

It takes one hour for mail with attachments to arrive

If mail is to another character *In same account* , its instant,
If different account, it will take 1 hour as shred said .
