Administration Joomla! 4.x • Re: Could not instantiate mail function.

This functionality was working fine a couple of months ago but today it fails. WHY??

Hi.

This is a problem on the hosting side - contact support.
It happens that hoster turns off the PHP Mail function if the site is suspected in spam, which often happens when using Acymailing.

When using Acymailing, knowledge of the domain mail working processes and antyspam policy of the e-mail services is required for fine tuning.

Frequent reasons for this:
1) Using a private email for the site, such as xyz@gmail.com - should be xyz@your-domain.com.
3) Lack of resource records such as DKIM, DMARC.
4) IP of your site is in the antyspam data bases.
5) The subscription form is not sufficiently protected.
6) There is no confirmation email of the subscription for the user (Double Opt-In).
7) Hacking your site with the introduction of malicious
8 ) The use of mailing is prohibited by hosting rules. Very often found. Before using Acymailing, you should read the Hosting Rules.

SMTP method is more reliable/secure than PHPMail.

Is not. This is an order of magnitude more slow and only because of this is considered safe. And not suitable for Acymailing
