E-Mail Troubleshooting


#1

I am trying to setup a UCM6204. My smtp server is provided by ionos.com. I have tried every combination of settings, but I can’t get the Test e-mails to work. How can I troubleshoot what is going on?

Show a screenshot of the settings you are trying to use.

Here is the screenshot for my UCM6204 e-mail configuration:

IONOS is my e-mail supplier. The SMTP server works fine with Thunderbird on my laptop. I can’t get the SMTP server to work with my UCM6204.

Any suggestions?

I changed the SMTP Server to read “smtp.ionos.com:587”. That solved the problem!

Thanks for the hint.
