tuxsub This solution helped me, in admin panel>emails in the email account I've set up, I've enabled Outgoing (SMTP) option, and the problem was solved. The sent emails are now readable.

I've struggled a bit with finding the correct settings but for me worked the port 587 with Basic authentication.

Then in Admin panel > Emails > Settings I've changed the Default MTA option to the email account I've set up, before setting SMTP to this email account, the only option in the dropdown was "None- use PHP mail function"

    I've tried everything herein with success, but the MIME problem persists. Is there something that I need to change in the program files perhaps?

      No, you just need to ensure SMTP is setup and working properly. You also need to ensure the Default Outgoing Email and Default Alert Email are set to an email with SMTP setup and working. You also need to ensure every Department's Outgoing Email and Auto-Response Email are set to an email with SMTP setup and working.

      Cheers.

        SMTP using MS OAuth2 is connecting ok for me, and Im also getting these MIME emails.

        However, if I send a Diagnostic test email from one of the SMTP addresses the email comes through fine, whereas the default SMTP address has the MIME.. so the two Emails must have different settings but I cant see - I'm comparing side by side..

        MTA is set to the SMTP not PHPMail... and the default SMTP is the wrong with the MIME problem.

          Are you using Modern Auth? If so, check the Token tab to see if the token has expired.

            I am also having this issue; osTicket was installed in a cPanel (1.17-git).
            Emails I send from my support email come through as a MIME Format; emails sent to my 'Alerts' email are also in MIME Format.

            I have setup 'Remote Mailbox' and 'Outgoing (SMTP)' as well as set the authentication methods, but still have the MIME issue. Further, my emails are getting marked as spam by my recipient's mail server (my personal email @live.com).

            Here is what finally worked for me:
            REMOTE MAILBOX
            Hostname: ssl://imap.stackmail.com (from my host)
            Port Number: 993
            Mailbox Folder: INBOX
            Protocol: IMAP (from my host)
            Auth: Basic Authentication (with my account login info)
            OUTGOING (SMTP)
            Status: Enable
            Hostname: smtp.stackmail.com (from my host)
            Port Number: 587
            Auth: Basic Authentication (with my account login info)
            NOTE: I had to make sure to select 'Basic Authentication' and NOT 'Same as Remote Mailbox' as this threw an error.

            Then, head to "Diagnostic" (under the "Emails" button) and send a test email; this should work for you.

              What is the Email Name? It has to be a name without special characters. Try updating the name to an actual Name and retest.

                Hi. I'm experiencing this issue. I have configured my support account in Agent Panel > Email Addresses for IMAP and SMTP and that seems fine. However, I still only have 'None: Use PHP mail function' in Agent Panel > Email Settings and Options > Default MTA. Tests sent using the diagnostic tool and any notices, replies etc from the system all have the mime issue. I have many other applications on the server using SMTP and PHPMail functions with no issue. Any other suggestions?

                  Apparently SMTP is not enabled still. Only emails with SMTP configured and ENABLED will show up in the Default MTA. Also, you can further confirm this by the MIME issue, this would not be happening if SMTP was properly enabled and working. Go back and review your SMTP settings for the email.

                  Cheers.

                      Sorry it took me so long to get back to this. I've checked SMTP settings everywhere I can find it. They look correct and save without error. I have verified the username/passwords as correct, still no option for choosing SMTP as the default sending method.

                          Hi,
                          Is there a way to fix this through the database?
                          I only have one admin account. I have not changed the username or password. I cannot log in to my account.
                          I tried the reset my password option, which sent me a mime link.

                          Is there another option to get back into the account?

                          Thanks!
