I just checked a couple of things. They appear to have 2 mail hosts
(mail-gw.zianet.com and mail.zianet.com).
I just tried to send to mail.zianet.com and it worked fine. I then
tried to connect to mail-gw.zianet.com and it failed (Connection
refused) I wonder if the failures happen when the 2ndary mailer
(mail-gw) is being used.
That could at least part of the problem. Also, can you paste any
failure messages from this ISP to the list ? Those will be of great
use.
