Hi, I have a zimbra server in production, first (a few months ago) I had problems configuring dns (MX record, etc.), later with the hostname (invalid HELO name: localhost) then I reinistall it with a correct name and I run BIND (FC4) for a right dns entrys. Once all that solved, always when I send an email to gmail or hotmail goes to spam folder of gmail/hotmail (and the first weeks my ip was listed at spamuhaus CBL list). I looked all the conditions my server has to aply for not be identified as spam.
I think all the configuration is right, my zimbra server is pointed by a router:
mail.mydomain.com -> 62.xxx.xxx.xx
62.xxx.xxx.xx -> router
router port 25 -> 192.168.0.xx
Any ideas? Thanks
(congratulations for this FANTASTIC software)
