**Your problem**  
My problem is: Email sending problem since Cpanel update to v94.0.2  
I have sent emails for years witt mautic without problems - since Cpanel update to v94.0.2 the problem started.

These errors are showing in the log:

Service to send mail through: Other SMTP Server  
SMTP Host: 127.0.0.1  
Port: 25  
SMTP encryption type: none

Here is log output:

Plz check if your port 25 is enabled. Seems you have a timeout.

I can telnet port 25 - output:  
Trying 37.97.xxx.xx…  
Connected to [mailer.xxx.com](http://mailer.xxx.com).  
Escape character is ‘^]’.

220-We do not authorize the use of this system to transport unsolicited,  
220 and/or bulk e-mail.

I can also send a testmail from the mautic configuration page which also arrives.

But when I start the sending process, no progress is displayed on the status page and I have these errors in the log file.

@galdon I have the exact same problem. It started when I updated Mautic to versión 3.2.5.

In my case I have now:

cPanel v94.0.4.  
CentOS 7.9  
PHP 7.4  
MySQL 5.7  
Mautic 3.3.1

I have tried several combinations with SMTP and It doesn’t send the emails with the same kind of errors you are shwing above.

Also, I have tried using sendmail and gets the following error for each email:

[2021-03-19 20:09:05] mautic.ERROR: [MAIL ERROR] Expected response code 220 but got an empty response Log data: ++ Starting Swift\_Transport\_SendmailTransport !! Expected response code 220 but got an empty response (code: 0) (send); NAME@DOMAIN {“exception”:"[object] (Swift\_TransportException(code: 0): Expected response code 220 but got an empty response\nLog data:\n++ Starting Swift\_Transport\_SendmailTransport\n!! Expected response code 220 but got an empty response (code: 0) at /home/USER/public\_html/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Plugins/LoggerPlugin.php:124)"} .

I updated Mautic to 3.3.1 and is the same situation. It doesn’t send the emails. I have used mautic for several years now and have no clue about how to fix this situation.

Could somebody help us on this???

Your host seems to have limited you, or have closed SMTP port. Reach out to your host support desk and ask. I think its pure coincidence this occurred upon an upgrade.
