Sentora Support Forums

I have 3 clients who cannot send and receive emails. My hosting provider is unreachable. Clients are desperate.
How can I solve this. In the past this has been a mailbox space issue. Can I increase the space from the zadmin control panel. Any help/ideas appreciated.

Are you able to telnet postfix? Firewall ok? DNS settings are ok?

We need more infos so we can help.
