    Umbraco Forms Error: MailKit.Net.Smtp.SmtpCommandException

    Hi,

    I have a strange issue with Umbraco Forms on my umbraco 11.4.1 Cloud instance, my form has been working fine, but all of a sudden the workflow audit shows a fail see image below there have been no changes deployed and comes with the following error code:

    enter image description here

    What SMTP service are you using? Does that have any more details for why it’s failing?

    Hi Kevin,

    Thanks for getting back to me on this, these are the SMTP settings within the Appsettings.json file:

    "Smtp": {
              "From": "[email protected]",
              "Host": "smtp.ionos.co.uk",
              "Port": 587,
              "DeliveryMethod": "Network",
              "SecureSocketOptions": "StartTls",
              "Username": "*************",
              "Password": "*************"
            }
    

    Username and password obviously commented out, double checked the username and password still no joy. The only error message receive is the one above, I've also tried with different recipient email address where I know the mailbox is available but still the same error message :-(

    UPDATE

    I've beenn messing around with the Umbraco Forms workflow, and think I might of stumbled across something when choosing a workflow for the form I am presented with the following options:

    enter image description here

    My current workflow which is failing uses a Razor template to send emails, if I just select the Send Email option and test everything works fine, so in conclusion looks like the Razor template is an issue I've tried the stand alone razor template in addition to my modified version and they both fail.

    It's a short-term fix for now using withotu Razor but ideally I would liek to use the template for the emails, here is the code below if anybody can see any issues:

    @using Microsoft.AspNetCore.Html
    @using Umbraco.Forms.Core.Extensions
    @using Umbraco.Cms.Web.Common.PublishedModels;
    @using ContentModels = Umbraco.Cms.Web.Common.PublishedModels;
    @inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Umbraco.Forms.Core.Models.FormsHtmlModel>
    @{
        //This is an example email template where you can use Razor Views to send HTML emails
    
        //You can use Umbraco.Content & Umbraco.Media etc to use Images & content from your site
        //directly in your email templates too
    
        //Strongly Typed
        //@Model.GetValue("aliasFormField")
        //@foreach (var color in Model.GetValues("checkboxField")){}
    
    
        //Images need to be absolute - so fetching domain to prefix with images
        var siteDomain = Context.Request.Scheme + "://" + Context.Request.Host;
        var assetUrl = siteDomain + "/assets/images";
    }
