I was getting a lot of spam so I decided to do something about it. After a bit of browsing I found that zen.spamhaus.org seemed to be what i needed so I did:
$ zmprov mcf zimbraMtaRestriction reject_invalid_hostname zimbraMtaRestriction reject_non_fqdn_hostname zimbraMtaRestriction "reject_rbl_client zen.spamhaus.org"
... and I was happy as my spam was filtered. Until I got to work and now I can't connect to Zimbra's web interface from work (Network Timeout). It works from home. The server is *not* on my home LAN so the problem is not there.
$ zmprov gacf
zimbraMtaRestriction: reject_rbl_client zen.spamhaus.org
I checked the IP address of my work place and it's not in any list:
Has this got to do with spamhaus.org? Any other spam advice?
