CommunityToolkit.Hosting.PapercutStmp

Overview

This .NET Aspire Integration runs Papercut SMTP in a container.

Usage

The Papercut SMTP integration exposes a connection string with the format endpoint=smtp://<host>:<port>. This connection string can be used to with a DbConnectionStringBuilder to get the smtp endpoint.

Example 1: Add Papercut SMTP with generated ports

var builder = DistributedApplication.CreateBuilder(args);

var papercut = builder.AddPapercutSmtp("papercut");

var xyz = builder.AddProject<Xyz>("application")
    .WithReference(papercut)
    .WaitFor(papercut);

builder.Build().Run();

Example 2: Add Papercut SMTP with user-defined ports

var builder = DistributedApplication.CreateBuilder(args);

var papercut = builder.AddPapercutSmtp("papercut", 80, 25);

var xyz = builder.AddProject<Xyz>("application")
    .WithReference(papercut)
    .WaitFor(papercut);

builder.Build().Run();

Example 3: Get URI from connection-string using DbConnectionStringBuilder

string? papercutConnectionString = builder.Configuration.GetConnectionString("papercut");
DbConnectionStringBuilder connectionBuilder = new()
{
    ConnectionString = papercutConnectionString 
};

Uri endpoint = new(connectionBuilder["Endpoint"].ToString()!, UriKind.Absolute);
builder.Services.AddScoped(_ => new SmtpClient(endpoint.Host, endpoint.Port));
