    Default Still Cannot Send Emails to Yahoo

    I'm running 5.0.11 on Ubuntu 6.06 64bit. I have several domains on the server that send and receive email perfectly. However, all email I send to Yahoo gets delivered to their spam folder. After hours of google searching I think it's because I'm hosting multiple domains on zimbra, all of which send from one IP.

    my mail server is mail.snapshotit.com and one of my domains is cfcpartners.com. The dns is setup correctly, spf is correct, reverse dns is correct. I've run the dnsstuff.com report many times and everything appears to be correct. I'm pulling my hair out over this....

    Can other people send email to yahoo on a zimbra server that hosts multiple domains? If so, did you do anything special to DNS or the server to get email through???

    Have a look at the full headers to see why they may have been blocked ? Also, Y! use DKIM and not SPF so you may wish to look at that aswell. I have just tested with my Y! account and email was received just fine. And yes I do host multiple domains.

    here is the header. I've asked this before and DKIM is not available in Zimbra yet. I assume that I'd need to setup a relay w/ DKIM, correct?

    Delete... posted wrong header.

    sorry - I've been testing this from many different accounts. Here is the correct header from my zimbra hosted email

    Code:

    It maybe because of
    Code:
    mail.snapshotit.com ([127.0.0.1]) by localhost (mail.snapshotit.com [127.0.0.1])
    What do you have in your /etc/hosts file ?

    The only thing I can suggest is using Postfix header_checks to strip out the localhost information. This has come up before so will have a dig and find the thread.

    Ya, I saw this post

    Keep Mail out of spam folder

    looks like he tried that and it did not work. I'll try it anyway.

    Are you using DKIM on your zimbra box - i.e. relaying through sendmail or other w/ DKIM setup?
