Unable to send emails in Azure WebApp utilizing Mandrill

Question

Hello Azure Community,

I followed the instructions in this article to setup Transactional emails using Mandrill: https://learn.microsoft.com/en-us/aspnet/core/blazor/security/account-confirmation-and-password-recovery?view=aspnetcore-9.0

The below code works on my local machine and sends emails via Mandrill successfully. When I publish the code to my Azure WebApp I get the below error.

When I comment out the Mandrill code and run on Azure everything works (except for the email being sent).

How can I successfully send emails on with Azure Web Apps using Mandrill?

Thank you for your assistance.

public async Task Execute(string apiKey, string subject, string message, string toEmail)

{

var api = new MandrillApi(apiKey);

var mandrillMessage = new MandrillMessage("******@axium.ca", toEmail, subject, message);

await api.Messages.SendAsync(mandrillMessage);

logger.LogInformation("Email to {EmailAddress} sent!", toEmail);

}

I decided to send the Transactional emails via my GoDaddy exchange server and everything is working now in Azure. Before doing that I also tried SendGrid but emails where getting blocked by Outlook.com

Microsoft states in the linked article above:

<< We recommend using an email service to send email rather than SMTP. SMTP is difficult to configure and secure properly.

I am using "smtp.office365.com" and it's working fine. Not sure why Microsoft leads you in the direction of ManDrill. I am open to someone elaborating on why Microsoft does this.

Thank you
