    Emails not sending in last update

    Hello
    Since the last update, it is no longer possible to send emails via the application.
    SMTP data is correct and has not been changed.
    The mail server and the server for the application are identical, encryption is not active and required.

      Hi pdpp,

      The issue with sending emails after upgrading to EspoCRM v9.1 has already been discussed on the forum in the following topics:

      Since updating 9.1 outbound mail functionality broke for me. Found in a another topic mail component was changed to symfony. Had a bit of a time getting that to work with my (local) SMTP gateway so figured I'd supply some freedback. First, the option of turning off encryption does not seem to work, even with it set to the

      It might make sense to look through them and get acquainted with the proposed solutions that have helped users.

      You can also share error logs of your EspoCRM instance, which will indicate a more specific error with sending emails. You can find logs in the {ESPO_DIR}/data/logs directory.

          Sorry, that doesn't help. SSL/TLS ist not needed if application and mailserver are on the same machine. If you use SSL/TLS there will be the same problem.

          This are the error logs:

              pdpp,

              Please tell me if I understand correctly that with the STARTTLS protocol, SMTP also does not work? Have you tried using other ports?

                  Yes, I tried all ports. 993 and 143 for IMAP, SMTP 465, 578 and 25. Nothing worked. The Problem might be, that there is a Let's Encrypt certificate.
                  Before the update, it worked with 143 and 25. Because no cerificate needed. Mailserver and Webserver is the same machine, though you do not need a certificate, because transport doesn't work with internet, only local.

                          I have this problem on one of my customer's EspoCRM and i found out that it's caused because Digital Ocean blocks SMTP ports. IMAP is working.
                          You can log in to your server CLI and run two commands:
                          ping smtp.gmail.com
                          telnet smtp.gmail.com 587

                          For my customer ping is working, but telnet is not.
