Can you please copy over the code you are using to send via PHPMailer!

Admin · November 25, 2021, 4:27pm

Googling the error message shows me other people get the same error with Yahoo:

github.com/mattermost/mattermost

SMTP with Yahoo: Connection unsuccessful: SendMail: 550 Request failed; Mailbox unavailable - undefined

opened 11:42AM - 20 Jan 20 UTC

closed 11:51AM - 20 Jan 20 UTC

Delawen

#### Summary I am trying to use yahoo SMTP to send emails. #### Steps to rep…roduce Configure a basic free Yahoo email on the SMTP settings and test it ("Test Connection"). See my configuration on the image below. An error will be shown (mine in Spanish): `Connection unsuccessful: Connection unsuccessful: SendMail: Error ajuste "Dirección Desde", 550 Request failed; Mailbox unavailable - undefined` Which may translate to: `Connection unsuccessful: Connection unsuccessful: SendMail: Error in settings "Email from", 550 Request failed; Mailbox unavailable - undefined` #### Expected behavior I should be able to send emails using that SMTP. #### Observed behavior (that appears unintentional) ![image](https://user-images.githubusercontent.com/726590/72723837-01c9a180-3b82-11ea-87ed-197afd5a97ff.png) #### Possible fixes Could be this? https://stackoverflow.com/a/51084780/469932

It seems that it’s caused by using an email address that you’re not allowed to send from your Yahoo address.

I don’t see exactly which email address is the problem, I think it’s [email protected] looking at the logs, but I don’t know for sure.

[email protected] is the recipient

Oxy · November 25, 2021, 5:52pm

@aslanmira never share publicly passwords (SMTP app pass) and your secret key for ReCaptcha !

besides publish a bunch of email addresses publicly is just a call for SPAM

I edited your post and hid it
but it is best to generate new keys and app pass

aslanmira · December 1, 2021, 2:06pm

Any ideas?

Greenreader9 · December 1, 2021, 2:10pm

Can you share the code you are using to actually send the email?

aslanmira · December 1, 2021, 2:32pm

The code is up there in the thread

aslanmira · December 1, 2021, 2:34pm

This is using the standard phpmailer which is publicly available. I am just showing the config and the logs, everything else I didn’t code.

Admin · December 1, 2021, 3:42pm

Ask Yahoo?

Yahoo’s mail servers are returning this error. The code you’re using should just work and the configuration seems fine too. Why Yahoo says that the Yahoo mail box is unavailable is something only Yahoo can say for certain.

The script was developed with Gmail, and that’s what most people are using without issues. So if you’re unable to get this resolved, maybe try a different mail provider?

aslanmira · December 1, 2021, 4:33pm

I will try Gmail, thanks.
I will update with the resut

aslanmira · December 2, 2021, 12:03pm

Now I see a different message
I am using the recommended gmail setup
define(‘CONTACTFORM_PHPMAILER_DEBUG_LEVEL’, 4);
Debug level is verbose but I don’t see any error logs:

Are you doing everything as we described? So:

Have a Gmail account
Have two factor authentication enabled on the account
Use an App Specific Password in your site configuration
Have CONTACTFORM_SMTP_PORT set to 587 and CONTACTFORM_SMTP_ENCRYPTION set to tls

aslanmira · December 2, 2021, 4:32pm

Yes. I can confirm that all the setting I am used are as described in the instructions.

Have a Gmail account: Yes
Have two factor authentication enabled on the account Yes
Use an App Specific Password in your site configuration Yes
Have CONTACTFORM_SMTP_PORT set to 587 and CONTACTFORM_SMTP_ENCRYPTION set to tls

define(‘CONTACTFORM_SMTP_PORT’, 587);
define(‘CONTACTFORM_SMTP_ENCRYPTION’, ‘tls’);

Greenreader9 · December 2, 2021, 4:37pm

Is your SMTP hostname set to smtp.gmail.com?

aslanmira · December 2, 2021, 4:55pm

Yes, it is
