@swissboy1984 Hi,

I hope you are doing well.

Please share the Post SMTP diagnostic test report so I can reproduce this issue on my staging websites.

Thanks

Thanks for your answer !

The issue was with the [email] dropdown list field.

The values were : “Firstname1 Name1 <[email protected]>” “Firstname2 Name2 <[email protected]>”

Works fine with : “Firstname1 Name1|[email protected]” “Firstname2 Name2|[email protected]”

Best regards

@swissboy1984

let me reproduce this case and get back to you soon with updates.

Thanks
