套件：golang-gopkg-mail.v2-dev（2.3.1-2）

simple and efficient package to send emails

This package is an actively maintained fork of Gomail and includes fixes and improvements for a number of outstanding issues. The current progress is as follows:

   - Timeouts and retries can be specified outside of the 10 second default.
   - Proxying is supported through specifying a custom NetDialTimeout.
   - not yet: Filenames are properly encoded for non-ASCII characters.
   - not yet: Email addresses are properly encoded for non-ASCII characters.
   - not yet: Embedded files and attachments are tested for their existence.
   - not yet: An io.Reader can be supplied when embedding and attaching files.

Gomail can only send emails using an SMTP server. But the API is flexible and it is easy to implement other methods for sending emails using a local Postfix, an API, etc.
