My mail keeps falling into the spam folder. I visited Bulk Senders Guidelines (page by Google, explains what to do in case mail falls into spam folder) to see why they mark it as spam and all it said is that I need to have a valid Reverse DNS records (which I do), sign messages with DKIM (don't have this), create SPF record (I did as TXT record) and publish a DMARC policy (didn't do this yet). I tried the DKIM thing, but when I try to install the path I get: (I cloned this patch from a git repo) Code: PHP Parse error: syntax error, unexpected ''/etc/amavisd.conf'' (T_CONSTANT_ENCAPSED_STRING), expecting ')' in /home/erik/dkim/install.php on line 61 I also went to dnsinspect.com which gives a full DNS report and everything seems fine. You can see the report here. Any ideas why my emails end-up in the gmail spam folder?
