Hello Since many days i have been facing issues with the emails, ie whenever mails are sent / forwarded from my server ( in case a email account has forwarder set to @gmail) , gmail always rejects message and i get something like : "SMTP error from remote mail server after end of data: host gmail-smtp-in.l.google.com [126.96.36.199]: 550-5.7.1 [My server ip] Our system has detected that this message is\n550-5.7.1 likely unsolicited mail. To reduce the amount of spam..." I have the following setup :- 1) Server host is set as :- serverone.xxxx.co.uk (domain removed) My domain mail is hosted on google apps for domain and the server's main contact email (WHM/Cpanel) also belongs to this domain. 2) I have Set DKIM signatures and SP records too. 3) however when i run dig -x 188.8.131.52 i get 240.12.228.109.in-addr.arpa. 21599 IN PTR server109-228-12-240.live-servers.net. 4) While diagnosing the failed email i have found that many email that gets rejected have Sender IP: ::1 Router: dkim_lookuphost Transport: dkim_remote_smtp 5) Also some accounts that are using Google mx, they don't even get mails, however while checking mail delivery reports they have status as "Message accepted" and Transport "remote_smtp" Please help , iam struggling to get the solution, we are getting lots of complaints from our customers. Thanks in advance.
