Sometimes it does not send mail from wordpress! Help
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?
