Bugger! Recently noticed I'm not receiving email sent from my WordPress install. Password resets, comment notifications, etc. They work fine when sent to my ISP and work email addresses but not my personal email address. Both my personal and work email addresses are hosted via Google Apps. Work's is a premier package whereas mine is the free service.
My shared host has also been blacklisted at backscatterer.org. Not sure if this is connected or not. This is a pain. In addition my hosting provider seems to be having trouble with their client portal so I can't log a ticket.
Starting to think long and hard about a VPS instead of a shared host. Slicehost and Linode both look good. Cost wise I would be paying about three times what I am now but would receive 8 times the storage, 4 times the bandwidth, dedicated IP address and my own instance. Sounds like a good deal to me.
