A workaround is good, but working would be better. šŸ™‚ It may just be the forum doing this, but it looks to me like you have a non-standard dash in your `-ā€“send-mail-any-operation=true` line - try retyping those two leading dashes so they end up like `--send-mail-any-operation=true` You should end up with something like the following with extra info as to whatā€™s going on. ```plaintext Running commandline entry Finished! The operation SendMail has started Starting - Running SendMail Running SendMail took 0:00:00:00.019 Failed to send email: System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. => The remote certificate is invalid according to the validation procedure. Failed to send email: System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. => The remote certificate is invalid according to the validation procedure. Return code: 0 ``` * * * Alternatively, you could just follow this (which you probably already know). Try your Command Line feature again but use this (I know, it probably looks like what youā€™ve already done): 1. Select command ā€œsend-mailā€ 2. Remove everything from ā€œTarget URL \>ā€ 3. Paste this in Commandline arguments: [--send-mail-to="xxx@gmail.com](mailto:--send-mail-to=%22xxx@gmail.com)" ā€“send-mail-url=smtps://smtp.gmail.com:465 [--send-mail-username="xxx@gmail.com](mailto:--send-mail-username=%22xxx@gmail.com)" ā€“send-mail-password=ā€œxxxxā€ ā€“verbose ā€“log-level=profiling 4. Click ā€œEdit as textā€ next to ā€œAdvanced optionsā€ and delete everything in that text box. 5. Click the `Run ā€œsend-mailā€ command now" button * * * Lastly, did any of the topics below work for you? I know gmail works because Iā€™m using it on one of my machines. Unfortunately that machine is not on-site so I canā€™t check my settings but I do recall having to fiddle with using `smtps://` or not and adjusting the ports on `--send-mail-url` to get things working. > [@Setting up email via web-interface not working SOLVED](https://forum.duplicati.com/t/setting-up-email-via-web-interface-not-working-solved/669): > > Hi, iā€™m new here, and new to Duplicati.
