Gomail
gomail is a Go SMTP client library used for composing and sending email messages through SMTP servers. It functions as an email message composer and MIME email serializer, converting complex email objects and binary attachments into byte streams according to internet message standards.
The library includes an SMTP connection manager that handles server session authentication and transmits multiple messages over a single encrypted connection to reduce network latency. It supports secure email delivery through encrypted data transmission to protect sensitive information during transit.
The project covers email composition, including the creation of multipart messages with plain text and HTML versions, custom headers, and external file attachments. It provides infrastructure for MIME-compliant serialization and the transport of messages via the standard mail transfer protocol.
Features
- SMTP Message Transmission - Provides a complete Go implementation for composing and delivering electronic mail via the Simple Mail Transfer Protocol.
