[enhancement]: Krb5 via GSS-API (Kerberos)

[Gabgobie]

Which feature or improvement would you like to request?

Hi,

thank you for this awesome project! I'd like to request support for krb5 authentication via the gss-api.

I am working in a FreeIPA domain and haven't seen krb5 listed under the supported mechanisms. The only feature request I could find that mentioned the GSS-API was #27.

This feature request concerns both your mail_send crate as well as the mail-server. I came across this project during my research for a way to integrate SMTP into my own little project.

Over the past months I have familiarized myself with Postfix and Dovecot to the point of being able to get them running with Kerberos but I wouldn't mind modernizing our mail infrastructure and taking a better look at this project, especially considering the goals you set out to fulfill.

Best,
Gab
