[arch-general] Does anyone receive two copies of same message on the arch-announce list?

Hello. Every time there is an announcement on the the main I'll get an email (as I am on the arch-announce list). However, about 5-8 hours I'll get another copy of the email. For example I got the [arch-announce] Pacman update and mirrorlist email Sunday at 23:00 and then today at 05:02. This has been happening for a few months now. I've checked the mail headers and each email is being delivered to the same address. Does anyone else have this problem or am I just lucky? ~pyther
