Georgia EPD-IT Email Service Library

This library was created by Georgia EPD-IT to provide common email services for our web applications.

Installation

To install, search for "GaEpd.EmailService" in the NuGet package manager or run the following command:

dotnet add package GaEpd.EmailService

Usage

The IEmailService interface provides a single method, SendEmailAsync(Message message), which sends an email Message. Typical usage would look like this:

// Create the email message.
var message = Message.Create(subject, recipientEmail, textBody, htmlBody, senderName, senderEmail, [ccRecipient]);

// Send the message.
await emailService.SendEmailAsync(message, token);

Note: While the sender name and email must be defined separately, the recipients (and CC recipients) can be formatted as a string with both user and email, i.e., "User Name <[email protected]>".

Configuration

The AddEmailService() extension method can be used to register the included implementation with your configuration settings. The DefaultEmailService implementation uses MailKit to send emails.

builder.Services.AddEmailService(builder.Configuration);

The following configuration section should be added to your configuration file:

{
  "EmailServiceSettings": {
    "EnableEmail": true,
    "SmtpHost": "localhost",
    "SmtpPort": 25,
    "SecureSocketOption": "Auto",
    "DefaultSenderName": "Default Sender",
    "DefaultSenderEmail": "[email protected]",
    "EnableEmailAuditing": true,
    "AuditEmailRecipients": [
      "[email protected]"
    ]
  }
}

• EnableEmail: Set to true to enable sending emails.
• SmtpHost: The SMTP server to use for sending emails. (Only used if EnableEmail is true.)
• SmtpPort: The port to use for the SMTP server. (Only used if EnableEmail is true.)
• SecureSocketOption: The MailKit SecureSocketOption to use for the SMTP server. (Only used if EnableEmail is true.) Available options are None, Auto, SslOnConnect, StartTls, and StartTlsWhenAvailable. See the MailKit documentation for a description of each option.
• DefaultSenderName: The default sender name (optional, can also be set per message).
• DefaultSenderEmail: The default sender email address (optional, can also be set per message).
• EnableEmailAuditing: Set to true to enable sending audit emails (useful for testing purposes).
• AuditEmailRecipients: A list of email addresses to send audit emails to. (Only used if EnableEmailAuditing is true.)

Note that EnableEmail and EnableEmailAuditing operate independently of each other. You can enable or disable each feature individually.
