Hello Guys ,
i'm using a mail solution based on roundcube, and when i send an email to an ( gmail , yahoo , hotmail ) account , i recieve it in the SPAM folder
My domain and my IP is not blacklisted ( i verrified both )
and i verrified the SPF record, it is well configured ,
Any solutions please ?

Thanks

Is Roundcube setup to send emails using SMTP? Do you have DKIM setup?

Gmail should give you a reason for putting it in SPAM. Not sure about the other services. Check the email headers, as that may show some info from the spam filter.

Please try to send an e-mail to mail-tester.com
It will tell you everything wrong with your setup.
Most probably it's no DKIM and no reverse dns. Both are required to have your mail accepted with a lot of providers.
