Hello, I apologize in advance because my problem is not strictly related to postfix, but I don't know another mailing list with helpful people with enough knowledge of the of the subject.
I have my personal emails handled by my own setup hosted on a virtual private server. Since a while (I believe it is now a year or so) Gmail classifies all my emails as spam. I believe I correctly setup SPF and DKIM, and the headers in the messages as received on the Gmail side seem to suggest that Gmail correctly validates both of those checks. However, this does not not seem to help in making them going through. The volume of email I send through this server is extremely low (it handles only my personal email and I'm the only active user). Currently I'm able to send emails to my address @gmail.com from the email address I'm currently using without having them classified as spam, but not from any email address having a different local part. I believe this is because my @grinta.net email address is white listed for my @gmail.com email address. Of course, Google does not care about the issue. There is something I can do to have my emails accepted by Google? Thank you very much. Cheers, Daniele
