I'm been trying to understand why Gmail is treating the email sent from one of my domain/server as SPAM. I found a lot of threads here about this issue, however I checked the usual suspects like domain keys, spf etc.
My email is accepted by Outlook.com, which from my understanding has a lot more aggressive spam filter.
I tested my config using [email protected] and I got this:
SPF check: pass
DomainKeys check: neutral
DKIM check: pass
Sender-ID check: pass
SpamAssassin check: ham
Everything looks fine.
After sending an email to a gmail account I get this under the headers:
Received-SPF: pass (google.com: domain of [email protected] designates 89.x.x.8 as permitted sender) client-ip=89.x.x.x;
Authentication-Results: mx.google.com;
spf=pass (google.com: domain of [email protected] designates 89.x.x.8 as permitted sender) [email protected];
dkim=pass [email protected]
As you can see, the email is passing on spf and dkim without issues on gmail servers.
Finally I checked my server IP, hostname and domain at http://mxtoolbox.com/blacklists.aspx for RBL blocks and they're not listed anywhere.
Why is gmail treating my emails as SPAM? It makes no sense, I've complied with every single good practice.
Other Note:
- Reverse DNS is also ok;
- Tests at

Thank you.
Apparently after a few days it start working fine.
Right now, I guess what really matters in GMAIL is actually passing this tests:
And wait 3 or 4 days so google can update their servers. Seems like the spam filter does some kind of internal cache on
DKIMandSPFlookups for a particular domain.UPDATE: This problem seems to be back, I've no ideia how to fix it.
