How to send email with Gmail SMTP

Outgoing email with PHP mail() is heavily restricted on InfinityFree. Fortunately, you can still whatever email you want using an external email service. There are many external email providers to choose from. InfinityFree doesn’t restrict sending email with external providers. Almost all of them have paid plans, but some have free tiers too. Most of them support sending email over SMTP, some of them have custom APIs, libraries and plugins which you can use too. A simple way to get started qui…

@Hamzadev

[email protected] email address not allowed

This did not look like a valid email

@Hamzadev

[email protected]’ email address not allowed

Are you sure you own this email as well?

You are better off getting support from Elastic email

$mail->Port = 2525;

Take note of this too:

@Admin

Please make sure to use port 587 (with STARTTLS authentication). Most SMTP services support port 587, and other ports (25, 465, 2525, etc.) are blocked on our servers.

Maybe port 2525 works, I haven’t actually tested. I would still recommend to use port 587 because I am sure that it works, but if it’s not giving you issues, then all is fine.

As for the issue itself, the error is returned by Elastic Email, so I’m guessing that it’s a configuration problem with what they need on their end. My first guess would be to check the allowed sender domains in Elastic Email and make sure that the domain arabx10.kesug.com is setup and verified there as a sender domain.

All transactional email providers I know require you to link and configure your domain name to send email from it. So sending email from [email protected] is definitely not allowed because you don’t represent gmail.com (and neither does Elastic Email, which would cause problems for them too).

I changed the port to 587 and it worked for me. Thanks for the help.
