Hi, I am a new user of zimbra and I have installed Zimbra 7 (ZCS). After configure zimbra and put the ISP Host in the MTA values, I have sent a test email to my gmail account. This mail does not get ever. Looking at the log I saw the following error message:
- " host hostisp.com[IP de ISP Host] refused to talk to me: 451-the server has reached its limit for processing requests from your host. 451 please try again later"
Does anyone know what happens? Or if I'm missing something in the configuration?
My idea is to send and receive mail through the hosting. To receive I use fetchmail.
Sorry for my English, I am Spanish.
I hope your help. Thank you
