I have installed ZImbra Collaboration Server (Version 8.5.1_GA_3056.FOSS) on Ubuntu 14.04.1 LTS.
I’m trying to enable milter server but I haven't managed to do it:
When I execute “zmmilterctl start” I get “Starting milter server...done.”
When I execute “zmmilterctl status” I get “Milter server is not running.”
and on milter.log I get “Unable to start milter server com.zimbra.common.service.ServiceException: system failure: Could not bind to port=7026 bindaddr= ssl=false useChannels=true”
Could you please help me?
