Trouble Configuring Email Sending in Mautic: SMTP Connection Issue

Product Support
1

Hello Mautic Community,

I’ve been trying to set up email sending in Mautic, but I seem to be facing some issues with the SMTP configuration. I’ve followed the documentation carefully, but I keep encountering an error message indicating that Mautic is unable to establish a connection with my SMTP server.

Details:

  1. SMTP Server: I’m using smtp.example.com as my SMTP server.
  2. Port: I’ve tried using different ports (e.g., 25, 465, 587), but none seem to work.
  3. Encryption: I’ve experimented with both SSL and TLS options.
  4. Credentials: I’ve double-checked my username and password for the SMTP server, and they are correct.

Error Message:

The specific error message I’m encountering is “SMTP Error: Could not authenticate.”

Troubleshooting Steps Taken:

  1. Checked SMTP server settings for accuracy.
  2. Tried different combinations of ports and encryption methods.
  3. Verified that the SMTP server is accessible from my network.
  4. Reviewed Mautic’s documentation and forums for similar issues but haven’t found a solution yet.

Request for Assistance:

Could someone please advise on how to troubleshoot this SMTP connection issue further? Has anyone else encountered a similar problem and found a resolution? Any help or insights would be greatly appreciated. :pray::slightly_smiling_face:
