FWIW: I am also using earthlink as my ISP. Earthlink is sure picky with my mail list (dada) which is a great program, but those with earthlink addresses get this message:
"This email included an attachment which EarthLink identified as containing a virus known as Malformed container violation."
Which is a bunch of &*&)^( - first, there is
no virus known as "Malformed container" and also it causes fear and trepiditation (on-line version of shock and awe) for my receipients. The list is on wwwroot2.
I've gone round and round with earthlink, but have better luck talking to the wall.
I think earthlink has a thing against PZ servers or the mail setup. Do you get PZ mail with other addresses (i.e. non-earthlink routings)?
