Regular error in mail sending

HI @lemouz,

The error message indicates that the email from your site is sent from an invalid email address that your SMTP server do not allow. You can check the ‘Force From Email’ in WP Mail SMTP settings which ensures that all the email are sent from the email you’ve added in From Email which should be your authenticated email.

I hope this helps!

Thanks, I’ll test this.
I also received this error this morning….

Mailer: Autre SMTP
SMTP Error: data not accepted.

Hi @lemouz – It is likely a similar issue. The incorrect or invalid ‘From Email’ is not accepted by your SMTP server. Please make sure the ‘From Email’ is the email address you’ve authenticated. Alternatively, you can check the ‘Force From Email’ option as described above.

I hope this helps!

Thanks,
Same error again.

I am not sure about the “mail authenticated”
Email in WP SMTP was [email protected] (with xxxxx.fr is my domain on OVH) which is not the same as the one in the WordPress administration (which is [email protected])
I tried to change this last one to another [email protected]. This works.
I then tried to change it to [email protected] but then no confirmation mail received to confirm the wordpress administration mail change( nothing in spam of course).

I precise that when I send a mail FROM [email protected] to the hotmail adress this works fine and I receive it.
The WP SMTP configuration is :
– other
– ssl0.ovh.net
– encryption : TLS
– port : 587
– SMTP login : [email protected]

Hope you can help (and thanks again)

Hi @lemouz,

Thanks for the details! Your SMTP login should be the ‘From Email’ sending the email which is [email protected] and it may not necessarily be the WordPress administrator email address. The original email message indicates the From Address is incorrect. So, please add the [email protected] in the From Email of WP Mail SMTP settings and check the ‘Force From Email’ option so that the ‘From Email’ set by other plugins are ignored. This should fix the issue.

I hope this helps!

I did it . But still same error.

Could it be an issue of wordpress unable to send mail with [email protected] which is under OVH ?

Hi @lemouz,

Thanks for the confirmation. There is no known issue with WordPress and OVH. It looks like there’s some configuration within your SMTP account. Please contact your SMTP provider with that error log.

Have a good one!

Thanks, I’ll try to test bu using other SMTP provider than OVH

Hello,
I am receiving the same message as above. I think I fixed it, but I want to make sure.

If I understand what you explained in your previous comments, the “From” email address should match the “SMTP Username” email address, correct?

From Email: [email protected]

SMTP Username: [email protected]

Thanks!
Best Regards,
Nancy

Hi @vogelne,

that’s correct. Those fields should match. And it’s also recommended to enable the “Force From Email” checkbox to make sure all emails will be sent from the same email address (which will improve email deliverability).

Have a nice day!

Hi @lemouz – We haven’t heard from you in about a week, so I’m going to go ahead and mark this ticket resolved. If you still have questions, though, please feel welcome to continue the conversation.

Hi,
As checking everything from the initial configuration (WordPress to OVH SMTP service), I change to use Google one.
It works fine since then.

For me the ticket is resolved.
Thanks all for your help

Hi,

I’ve juste updated WordPress from 5.5 to 5.6, it maybe a relation ?
