Installing Zimbra the right way? (not being blacklisted)
Hey Everyone
So There are loads of guides online on how to install zimbra and that bit is fine,
but how can you do it all completely the right way including DNS?
because I am forever marked as spam when I email people and i just don't get why,
I have used mxtoolbox etc etc to try help but still with no luck.
for safety purposes I'm not going to put my own domains but I have the following setup:
server record is zimbra.mydomain.com
then I have other domains such as below for example
mypersonaldomain.com
mybusinessdomain.com
each of my domains have DMARC DKIM etc etc all tested through mxtoolbox.
I just need my email to not be spammed with everyone I talk to.
Any help is massively appreciated

Re: Installing Zimbra the right way? (not being blacklisted)
The problem here is that you've given no information that anyone can check. I'd suggest you talk first to some of the people that receive your mail as spam the try and get them to send you all the headers from several email or, at the very least, get them to tell you why you are blacklisted. You could send my server an email and I'll see what it tells me, if you like. Send me a PM and I'll tell you my email address, I'll also take a lookl at your domain DNS records and RBL lists as well if you want.. Oh BTW, an alternative would be to send an email to a google or yahoo account and see if that ghts triggered as spam then look at those headers.
Re: Installing Zimbra the right way? (not being blacklisted)
In my experience if I don’t ask my provider to setup the reverse DNS pointing to my domain, all my sent emails go to spam (unless I use an authenticated SMTP service).
For multiple domains I don’t know if the reverse DNS can be created.

You don't need a reverse IP for each domain, there's a complete and simple description here (it also saves me typing):milauria wrote:For multiple domains I don’t know if the reverse DNS can be created.

Re: Installing Zimbra the right way? (not being blacklisted)
Wow thanks for all the comments everyone
I will send to my alt email accounts and take a look at the headers.
I have my ptr records setup correctly to my primary domain on the server so that's another
I'll update you all when I have tested emails to my alt emails.
Thanks again

Re: Installing Zimbra the right way? (not being blacklisted)
Hey guys so it looks like I have got it all completely wrong,
I following the zimbra guides so im not sure why,
It failed on:
SPF with permerror
DKIM FAIL
DMARC FAIL
I will make another attempt.

Re: Installing Zimbra the right way? (not being blacklisted)
hey everyone
so after some tweaking I now have passes for SPF, DKIM and DMARC
BUT hotmail is still spamming me
anything more i can do to make sure i'm not marked as spam?
my server is correctly setup with PTR records aswell.
Thanks for all of your help!

Re: Installing Zimbra the right way? (not being blacklisted)
Give us some evidence of what the headers show. Merely saying that 'it's not working' doesn't actually give us much information, does it?

Register your ip's with them. Every big provider seems to have their own hoops and this is what outlook/hotmail/etc required at one time.
Another option is to stop playing the game and all the hoops the big mail operators require and use one as a smart relay that is too big to block/spam classify on ip reputation alone. With paid for gmail at $5/month, you can get 10K recipients per day. They allow you to set up a smtp server to relay through.
