Hi, I hope you're well. I have a question, on my server I have installed wordpress and I have also installed what is the postfix SMPT mode to only send mail notifications and I work perfectly mailing, but I have a small drawback is that I have noticed that In wordpress I have users who have not confirmed their mail and I have several users who have told me that the mail has not arrived, while another if they arrive. It happens that I have the SPF and the DKIM correctly configured, but I still send the mails in SPAM, but the inconvenience is the Why is not sent or do not reach others?

After setting up SPF and DKIM, do you have to wait for some time for the mail providers to consider you reliable even if you have the SPF and DKIM correctly?

Yes, you have to wait some time after setting up everything, to build reputation with mail providers. That's normal.
In that time some mails will get delivered successfully, right in the users inbox, but some will end in spam folder or even not delivered.

Beside SPF and DKIM, you should also set up PTR record. PTR record will enable reverse lookup for your domain, so mail provider can resolve your domain to IP address and verify is sender correct.
To do it on DigitalOcean, change hostname in Cloud Control Panel to your domain name. In Networking -> PTR records, you can verify is it added successfully.

Also you can "register" your email domain with some of mail providers. [This ServerFault] answer links needed steps for some of mail providers.
