• NA megaservers for maintenance – December 23, 4:00AM EST (9:00 UTC) - 9:00AM EST (14:00 UTC)
• EU megaservers for maintenance – December 23, 9:00 UTC (4:00AM EST) - 14:00 UTC (9:00AM EST)
Pretty sure thats how it works, although I tend to give things away mostly so I don't have much experience with the COD setting on mail.
I will point out that there seems to be a small delay sometimes with mail, so don't freak out right away if you sell an item and it appears you did not get paid, or if it looks like your friend did not get it. /reloadui usually makes mail pop up.
There is also the guild store option if your in a guild with more then 50 people (I believe), and you can use it by going to any bank teller.
