Email message is not visible...but it is attached!

[shinesoftware]

Magento version #:

2.3.4

Edition (EE, CE, OS, etc):

CE

Expected behavior:

Read the email message content

Actual behavior:

After the last update the text message content is hidden and a file (attachment.html) is attached to the email as shown in the image.

Steps to reproduce:

Run the test and check the Hello from MagePal SMTP (2 of 2)

I'm not able to reproduce this issue using Magento 2.3.4 (with Gmail), so this would require further debugging

[shinesoftware]

Yes it is really weird! I have a different behaviour in local enviroment and in the production enviroment. Do you have a clue? Why the test sends two messages? which is the differences between them?

[shinesoftware]

I am debugging the code and I have discovered this weird behavior using your module. Check the image.

After a little debug I have noticed that the composer version v2.7.1 generates the issue that I have posted here. After the installation by a simple copy of the module in the "app" directory I can receive the message email correctly. The version installed is the 1.5.1. Any clue?

The issue is related the UTF8 encoding of the message set in the latest version of the module. Seems that the encoding breaks the message structure and the email client shows it as mentioned before, as attachment.

... maybe you have to describe why you force the code to use the utf8. please review the file with a better solution.

With this patch the module works like a charm!

I am not sure if the issue I have just raised is related #166

No because we have not that error:

PHP Fatal error: Uncaught Error: Call to a member function setEncoding() on bool in /var/www/vhosts/domain.com/vendor/magepal/magento2-gmailsmtpapp/Model/TwoDotThree/Smtp.php

This issue should be fixed in 2.8.0 which will be released shortly

[srenon]

@shinesoftware ... what email client (webmail, Mac Mail, Thunderbird, Outlook etc) are you using?

Please download 2.8.0 and let me know if you are still having issues

[shinesoftware]

I am using the zoho.eu mail server. I'll check your latest version asap!

[shinesoftware]

Please download 2.8.0 and let me know if you are still having issues

@srenon the dev-master alias 2.8.0 works! Thanks guys!
