Liham AWS SES Inbound/Outbound Email

December 23, 2019

Liham is a Filipino word that means letters, or mails. it is a simple Serverless Mail Client that allows you to receive E-Mails with your custom domain using the Amazon Web Service (AWS) infrastructure, without maintaining any servers.

Sample Use Cases

A User sent an e-mail to bot@domain.com, this e-mail contains an excel file that needs to be uploaded to the database using Extract Transform Load.

Liham can then received this e-mail by utilizing AWS SES this e-maill will then be processed from RAW format to JSON format.

Liham will then put the JSON formatted e-mail to the email folder of bot@domain.com.

Once the e-mail in the JSON format landed on the email folder of bot@domain.com a lambda function can then process it, triggered by the S3 Notification Configuration. The lambda function will then extract the Base64 Encoded Excel File from the JSON file.

After extracting the Lambda function can process it then upload its contents to the database and sent an automatic upload report back to the sender.
