Notes

  • Users with a Sugar Labs shell account on sunjammer can use our SMTP relay for personal email submission. Any abuse will be prosecuted.
  • The submissions port (465) is preferred for email relay. Unauthenticated and unencrypted connections are not allowed to relay.
  • All email for the sugarlabs.org domain must be submitted through our SMTP server. Failure to do so may result in your email being blocked by spam filters.

SPF

Our domains use a non-strict (~all) SPF record.

DKIM

Our domain publishes a DKIM key.

To test DKIM, send an email to autorespond+dkim@dk.elandsys.com
