smtp error

Giancarlo Tonti — Tue, 12 Nov 2024 10:11:40 +0000

On send of the message I have this error

SMTP Error: The following recipients failed: [email protected]: No Such User Here

[email protected] is a sample, not the real one.

The problem is that che recipient exists and works fine.

How can I fix this?

SMTP Error: data not accepted

HI,

Sending emails with MailPoet has not worked for a few days. The attempt pauses with the following error message:

SMTP Error: data not accepted. Subscriber not processed (<***@***>)

The sending mode is SMTP, the MailPoet version is 5.3.3
By deleting the subscriber from the list, the problem occurs on the next one.
I sent a test email via the MailPoet settings and the mail arrived correctly, so the SMTP configuration is correct.
I contacted the server that hosts the site, Aruba, and they confirmed that the configuration is correct and there are no problems.
I also read the page https://kb.mailpoet.com/article/300-why-sending-is-paused-when-using-smtp but it didn’t help me.

I am having issues with WP Mail SMTP. I have the account set up. When someone submits a submission form from WPForms, they receive the submission form confirmation email, but the confirmation email for the company email will not send. Every time I run a test submission I get this error.

Hi,

I have installed this plugin few days ago and everything was setup and working fine. I didn’t change a thing since last night.

Today out of blue, the email stopped working on my desktop (Mac OS Mail), warning says: ‘Connections to host mail.mywebsite.com on the default ports failed’.

I can send and receive emails from cPanel Roundcube ok though.

In WordPress > WP Mail SMTP > Email Test > Send Email:
There was a problem while sending the test email.

The very annoying part is that I am in the middle of setting up a newsletter plugin!

Please advise if you can, thank you.

Hi, just installed fluent smtp to try it out.

To start, I chose to connect it to the server’s mail server (VPS) via the Other SMTP option.

I’m setting it up, but when trying to send test email I’m getting the error

SMTP Error: Could not connect to SMTP host. Connection failed. stream_socket_enable_crypto(): Peer certificate CN=' did not match expected CN=’

any ideas?

Thank you

I am testing email all users. I am getting this error when trying to email all users and also roles “SMTP Error: data not accepted. I am using fluent SMTP and randomly I get this error from certain users when they are trying to reset passwords as I am testing membership site. { “code”: 423, “message”: “SMTP Error: data not accepted.”, “errors”: [ “SMTP Error: data not accepted.” ] } I am using my own domain email for the SMTP authentication. I have tried others as well, I can test the email process and it shows works successfully. I am reluctant to move to the pro version if I cannot guarantee mail delivery. I have also tried wp smtp. do you have any thoughts on this?
