Mail notifications not working after PHP upgrade

[gregor5]

We upgraded PHP to version 5.6.36 and our mail notifications stopped working. Prestashop version is 1.6.1.18 and it doesn't matter if I have mail setting on "Use PHP's mail() function" or "Set my own SMTP parameters" ... mails are not going out.

 

Mail was working fine with PHP v. 5.4

This is what we see in mail error log:

Jul 10 14:41:34 mx01 postfix/smtpd[2098]: connect from xxxx.xxx.com[xx.xx.56.228]
Jul 10 14:41:34 mx01 postfix/smtpd[2098]: SSL_accept error from xxxx.xxx.com[xx.xx.56.228]: 0

Jul 10 14:41:34 mx01 postfix/smtpd[2098]: lost connection after STARTTLS from xxxx.xxx.com[xx.xx.56.228]

We are still having this problem - now with PHP 7.0.31 .

 

Anyone else had this issue? ... when I test sending mail using "Use PHP's mail() function" in the back-end (in Prestashop) I get confirmation that everything was fine and mail se

"A test email has been sent to the email address you provided."

 

 But the mail never comes... There is a log of outgoing mails in Prestashop that never came to these addresses. SMTP setting on the other hand gives an error.

 

Customers do not get any notifications.

 

please help

Any solutions so far? I have same problem...

 

I guess we need to do something like this solution:

They are using this code:

 

$config['smtp_conn_options'] = array(
  'ssl'         => array(
     'verify_peer'      => false,
     'verify_peer_name' => false,
  ),
);

there was something wrong with certificate - I server admin fixed it and I think this was the solution https://tinyurl.com/y8om89y3

Solved it!!! It was indeed a Certificate Issue. Postfix needs the Chain Certificate instead of the regular file!

 

Thank you.
