Line breaks are being removed if content-type is text/plain
-
Hi, I’m currently using FluentSMTP with a SMTP2Go connection to send emails, and I’ve noticed that line breaks are being removed from the messages sent with the header content-type: text/plain. The problem could be cause by the email body sanitize.
I found this problem receiving fatal errors email by the built-in feature in WordPress.
I’m not entirely sure if the issue is related to the SMTP2GO connection, but I thought it was worth flagging in case it’s relevant.
Thank you

Hello @ibrahimsharif
as requested i leave all the information below. I had to blur some sensitive information. They’re all email addresses or names.
The email content before it’s sent through FluentSMTP
I made this code snippet to replicate the problem.
add_action('init', function(){
$test_content = "This is the first line\n. This is the second line.";
$subject = 'Test Email';
$to = 'add address here';
wp_mail( $to, $subject, $test_content );
});The email content after it’s been sent via FluentSMTP/SMTP2Go and received in your inbox.
The new line becomes a blank space.
Your FluentSMTP settings.
The email headers, specifically the ‘Content-Type’ header.
It seems that it’s replacing the text/plain header with the text/html header.
I am currently using SMTP2Go with other SMTP plugins for WordPress and they work fine.
Thank you for you assistance.
