Re: DANGER: 8.8.15p20 broke working machine openssl

Hi Jim and everyone, How are you? We are planning to carry out this update this weekend but we should postpone it a bit :) BTW, our system is quite large (3TB mailstore servers). We have NGBackup.

Re: SMime Invalid Certificate Uploaded

Hi,
Maybe you can try to set zimbraSmimeOCSPEnabled FALSE:

Code: Select all

$zmprov mcf zimbraSmimeOCSPEnabled FALSE

Zimbra has a new SMIME Zimlet which is com_zimbra_securemail and is enabled by default. The old Zimlet is com_zimbra_smime should be disabled.
Regards,
Minh.

Re: Find the source IP address

Dear, I think you need to add all proxy server's IP into the list. For user in the LAN (I mean your local LAN), oip will show the LAN IP address. If there are any NAT between LAN subnet and the outside interface (for example, WAN IP address of internet router), the OIP is WAN IP address. Regards, Mi...

Re: Find the source IP address

Hi,
You need to add the proxy server's IP into the trusted IP list, as zimbra user:
zmprov mcf +zimbraMailTrustedIP 127.0.0.1 +zimbraMailTrustedIP <IP of proxy server>

Re: What is the best antispam for Zimbra?

Barracuda, mimecast, spamtitan, etc are some paid solution but they are quite expensive. You can have a look at spamhero or mx guarddog if you need cheap one.
Best regards,
