I have to say you might want to look into NOT using the WOW servers.
I had so many like issues with WOW email I just bought my own domain name and 6 email boxes. This is like $35/year and you might be able to find one cheaper as well. Having your own domain and being able to have whatever email name you choose is well worth $35/year to me. I no longer use WOW servers for anything except email from WOW.
I could also drop WOW and WOW, I still have the same email addresses. You can do this with some other free service but really, getting your own domain is not very expensive.
Insightful points, AES; I think you're right about avoiding use of WOW's servers. For now I solved the problem by changing to a different email provider's server, but maybe I should quit chasing my tail, get my own domain, and call it a day.
