[Evolution] Mail authentication request

["Dr. John H. Lauterbach" <john lauterbachandassociates net>]

I have the best Internet service I can afford (50 Mbps down /10 Mbps up, Cox Business Cable); however, it is too slow for evolution or perhaps the mail servers I am using are too slow. I am getting repeated "Mail authentication requests. How do I keep these from popping up or keep them from popping up when I acknowledge the first one?
