Hello everyone,
i have a spam problem that I can't understand and I ask for your help.
Iredmail mail server, send to port 26 of pmg and then send out.
All connected clients (pc, notebook) work without problems with MS Outlook, Thunderbird, EM Client, or other clients.
This is the third time i am blacklisted by Spamhaus because according to their email, a device (android) is sending spam emails.
After having done all the checks, I enabled the spam rule out and found the device.
This smartphone uses the gmail app as a client to send and receive mail via imap.
I installed and configured my address on another android smartphone using gmail as a mail client and also my email address is reported by pmg as spam sender.
Changing client for mail this doesn't happen anymore.
When I send via gmail client for android, pmg warns me with this message:
I checked spf and dkim and they are all positive for my ip and domain (I enclose dmark.jpg, spf.jpg and dmarc.jpg).
I also tried to insert _spf.google.com in my spf but it doesn't change anything.
I have hidden my public ip and the domain of my business.
The dkim inserted in the dns of my domain is the one generated by pmg.
Thank you all for your help and excuse my English.
