I always check my mail on the weekend, and if any bounce mail has less than 7 days on it, I take it out and remail it. Mail will only bounce once, then is deleted if it bounces again. By taking it out and remailing it, never letting it bounce, you always have a bounce in case you forget about, computer dies, internet goes down, etc. If the "return to sender" button is not lit, you know it has already bounced, and is due to be deleted.

Oh, I still do it. Just real careful with rare/more valuable stuffs. Khorium ore is probably the mother of all PitA things to farm. Wish they would have adjusted patterns accordingly.

It's also *not* actually unlimited. There is a limit on the number of mails you can have out at any given time; I hit the cap when I was mailing Winter Veil presents to my guild last December. You then have to wait for some of that mail to get opened before you can send any more.

@slythwolf Actually the limit is about 20 different characters that are NOT on your account, per 1-2 hours. You can send any number of mails to your own characters, with no limit that I have encountered. And I've loaded up my own mailboxes before.
