Hi, I have an emailform on my WordPress website that has been working fine for the past 3 years. Since the lastest update of Cpanel, I get an SMTP error My roundcube mail sends and receives emails fine and also receiving and sending emails on my phone works fine using the same SMTP host, port and authentication. The last lines of the error are line these: 2017-03-31 08:20:29 CLIENT -> SERVER: STARTTLS 2017-03-31 08:20:29 SMTP -> get_lines(): $data is "" 2017-03-31 08:20:29 SMTP -> get_lines(): $str is "220 TLS go ahead " 2017-03-31 08:20:29 SERVER -> CLIENT: 220 TLS go ahead 2017-03-31 08:20:29 SMTP Error: Could not connect to SMTP host. 2017-03-31 08:20:29 CLIENT -> SERVER: QUIT 2017-03-31 08:20:29 SMTP -> get_lines(): $data is "" 2017-03-31 08:20:29 SMTP -> get_lines(): $str is "221 server.budgetdomainnameserver.nl closing connection " 2017-03-31 08:20:29 SERVER -> CLIENT: 221 server.budgetdomainnameserver.nl closing connection 2017-03-31 08:20:29 Connection: closed 2017-03-31 08:20:29 SMTP Error: Could not connect to SMTP host. I checked and doublechecked the SMTP Options and they are still the same as in my Cpanel: SMTP Host localhost SMTP Port 25 Encryption No encryption (There is also the option for SSL and TLS encryption) Authentication Yes: Use SMTP authentication. Username I used my email address Password I use my corresponding password Why do I get an SMTP error since the last update on my WordPress ContactForm? Can someone help me out? Thanks!

  Hi, Can you check if SMTP restriction is enabled or disabled on the server. The update may have pushed it to be enabled..

  Hello, Could you browse to "WHM Home " Security Center " SMTP Restrictions" and verify if this feature is enabled? Also, you mentioned updating the version of cPanel. Could you let us know which version your system was updated to? You can check with a command such as:
  cat /usr/local/cpanel/version
  Thank you.
