    Default How to un-block spam from a domain I control

    I've got a server from which I send mail via an SVN post-commit hook. When it arrives at my Zimbra mail server it gets marked spam. I have complete admin control over both servers. Is there a way I can tell the Zimbra server to allow emails from my svn server either by IP address or some other way? Here is the header of one such email (domains and IPs replaced to protect the innocent):

    Code:
    Return-Path: www-data@devsvn.mydomain.com

    Wow! for a start do you really tag spam with a score of 1 You should also fix your SpamAssassin. Search the forums for FH_DATE_PAST_20XX especially with tagging at such a low score

    Thanks, while I have control over the server I did not actually do the setup. It was installed by a different contractor. I'm sorta taking over so I'll take your advice and read up on that.

    On your Zimbra server post the following
    Code:
    su - zimbra
    zmcontrol -v
    zmprov gacf zimbraSpamTagPercent zimbraSpamKillPercent

    The tag is very low indeed. You should have a read through Zimbra MTA - Zimbra :: Wiki

    It is possible the previous admin wished the tag score to actually be 5 but did not realise the value should be specified as a percentage of 20 (100%). If that is the case to change it
    Code:
    su - zimbra
    zmprov mcf zimbraSpamTagPercent 5
    zmamavisdctl restart
    You should also read http://www.zimbra.com/forums/announc...ity-issue.html if not already done so and look to perform a upgrade soon.

    Thanks a lot for the assistance. I am mostly a developer and was trying to get svn notify emails to work. This lead me into this spider hole so I'll pass this information along to my client and he can decide if he wants me or someone else to update and/or upgrade the server. It's an incredibly high volume server so there's nothing I can do during business hours anyway. I'll see about making these spam updates tonight after COB. Your help is most appreciated.
