Re: [Astlinux-devel] Mail API

[Lonnie A. <li...@lo...>]

Hi Michael,

I have heard good things about Mailgun, but have not personally used it.

When using the Mailgun SMTP Relay, is there only one auth credential per account, or could every unique API key auth the SMTP Relay?

Possibly different users in Mailgun would need to be created for multiple SMTP Relay credentials.

There are quite a few services that use sendmail (via msmtp), in AstLinux [1] the scripts sendmail.sh, msmtpqueue.sh, testmail.sh call 'msmtp'.

A dev could create an 'api-smtp' shell script, alternative to 'msmtp', that takes input like sendmail, produces error codes like sendmail, but uses 'curl' and  Mailgun APIs to send the message.
