Hello, I'm slowly getting stuck. I have now tried everything I need, but cannot establish a connection with PHPMailer.

aaP_drericlaufer Hello, are you using PHP for sending emails?
If so, you need to release port 587 for SMTP and install the php-SMTP extension

aaP_drericlaufer

yes, would like to do that with PHP.
how do you install this extension in the aapanel?
Sorry, but I'm not really familiar with your panel yet and it's also my first server

imap

aaP_drericlaufer

Hello,
have installed the extension.
but unfortunately i still get the same error as before.

aaP_office

Hi
I have a similar issue.
I am trying to send email from wordpress using smtp credentials for mail server hosted elsewhere.

When I try to install the imap extension is says its installing but then it reverts back.
I am running Oracle linux

Lobo

So what was the solution? I have installed imap extension as directed, port 587 is open as I can confirm with yougersignal.com, still can't connect with PHPMailer through SMTP from Wordpress install.
