Email smtp module issue

[APG1972]

Hello, 

I am unable to set official smtp and email Prestashop module after upgradind to version 8.2. I have tried many changes: ssl, tls, port... nothing happens, the error code changes but the email module cannot be set up. For example:

• This one when using TLS and port 465: Expected response code 220 but got an empty response
• This one when using TLS and port 587: Expected response code 250 but got code "550", with message "550-Requested action not taken: mailbox unavailable 550-Sender address is not allowed. 550 1N8GhM-1t3Zk01nXs-014jrK "

Another developer from my hosting serviceinstalled Prestashop from scratch and the result was the same.

Is there anyone with the same problem and got a solution?!

Thanks in advance.

Hi, the message is clear: 550-Requested action not taken: mailbox unavailable 550-Sender address is not allowed. What is you mail provider?

My email provider is Ionos.

The point is that when the shop was version 1.7.8. everything worked fine. After updating to 1.8.2. from a scratch installation, it failed.

TLS and port 465 - It's wrong. With TLS, the Port should always be 587.

With SSL, the Port should be 465.

It means "The Recipient’s Mailbox is Unavailable" OR it might be the issue with the "Sender From" details as well. Sender details is not allowed by the SMTP service. 

Have you tried with other SMTP details like Gmail etc. Also, check with the email service provider as well.

I haver tried with a Gmail SMTP and it works. So I guess the problem is in my email service provider (Ionos). But it´s very strange that the same setting worked with PS version 1.7.8.

Yes, the same settings. I have just tried with a gmail account and it works. So the problem should be in Ionos email service. Anyway, this is very weird.

Ask IONOS support

I have just talk to IONOS and they say nothing is wrong with the email service. So I guess there´s something collinding between IONOS and PS 8.2.1. (or its email module).

Solution: to use a gmail address and let´s seen in the near future if a domain email can be set up.

THANKS FOR YOUR HELP, GUYS!

Hello, do you try to configure with external mail or local? It can be a problem with external mai it can be not allowed by hosting, in this case you can trey to create a local email on this server and to configure it for SMTP it may helps.

Hello, Alex.

The email is hosted in Ionos, as the domain, so it´s a local email. But the point (you are right at that) is that it looks the hosting doesn´t allow the connection to PS. Weird, so finally I set Gmail up and it worked.
