After upgrading to magento 2.3.5-p1 emails are not sent

[Leo27]

Hello,

I've installed yesterday the last magento 2 version, 2.3.5-p1, after solving a few problems all apparently was fine, tried a few things (add to cart, sign in front store, etc), when I finally created an order to see if everything was ok, it wasn't, the order confirmation was not sent, neither to the client or the bcc copy.

Tried to send invoice email, shipping email and comments in the order, this last one showed me an error message "We cannot add order history.".

No emails were sent.

I tried to find some sollution, but without luke, I've obviously confirmed if everything was still correctly configured in stores/config/sales/sales emails it was.

I finally came back to version 2.3.4

Can anyone help me? any idea or anyone with same problem?

Any help would be apreciated,

Best regards,

Leonel Nunes

Hi @Leo27 ,

Please check the below points:

1. Go to Stores -> Configuration -> Sales -> Sales Emails

Under the General Settings tab, choose Asynchronous sending to Disable
Under Order tab Enabled to Yes

2. Go to Stores -> Configuration -> Advanced -> System

Under Mail Sending Settings make sure -  Disable Email Communications is set to No.

Also, verify your Host and Port fields if you are using any external mailing server.

Now clear/refresh your cache.

Also Please check do we get anything in the var/log related to the mails.

Thanks!

Hello @Leo27 

first of check your server email functionality enabled.

If yes then do setting as suggested by @Nishu Jindal 

If your server does not provide email thing then check with SMTP module, by using you can send email.

Hope it will help you.

if works then mark as solution

Hi @Leo27 

Try to install this free SMTP module:

Also check in admin panel configuration that the email is turned on. There could be chances that email can be turned off from the admin panel:

Stores -> Configuration -> Advanced -> System -> Mail Sending Settings -> Disable Email Communications to No

I've checked all the point you have mentioned, and also I'm using the magento/server mail server with no extrenal extension.

Also all is working with magento 2.3.4, after upgrading no email are sent..

In var/log there is no error

Hello Bhanuperiwal,

thanks for your help.

I really didn't want to use that module, in times with magento 1 I've tested it, that's not what I want, I prefer to use the php mail server.

In magento panel the mail communication is turned on,the disable option is set to no.

Best regards,

Hi, check if the email has an attachment, if yes then you will have to modify transport builder class used for email sending
