These tips are epic, I love them so much haha!
#1. Zero's Post on the JMTC forums on automatically openning up mail all at once.
"I decided to write a tiny addon that automatically checks for new mail (CheckInbox()) and opens all my current mails in my mailbox using Postal Open All. This addon will no longer require you to press any macro or button when you have loads of mails waiting to be opened but instead it will refresh your inbox every 10 seconds and attempt to open the current mail using Postal Open All (so it will be affected by the rules you change for that). I made it so I can go AFK when I have 500 or more mails waiting for me. Download here: http://zero.isimba.org/MailOpener%200.2.rar"
#2. Increase the speed at which mail loads with HitTheCap, Wow Journal about Hitting the Gold Cap.
