In the hope of streamlining account creation e-mail delivery and mailing list moderations, I have deployed SPF and DKIM over the weekend for e-mails coming out of @jenkins-ci.org, which includes account appliations, Confluence, and JIRA.
I've also used this opportunity to switch back the sender of JIRA notifications to firstname.lastname@example.org. It was originally this way, then changed to email@example.com when someone complained (on what ground I do not remember any more.)
To the degree that I have tested the setup, it is working correctly, but if you notice anything strange, please let me know. About the Author
