Implement DKIM for outbound e-mail
Short, concise description of the idea
LiveJournal should implement DKIM (aka DomainKeys) signatures on all outgoing mail.
Full description of the idea
LiveJournal should implement DKIM (DomainKeys) signatures on e-mail leaving LiveJournal. The reference implementation at http://domainkeys.sourceforge.net/ could be used. More general information on DomainKeys is available at dkim.org.
Notifications (Schwartz notifcations/comment notifications) could be signed with one signature, password reset/support notification/etc. emails could be signed with another, and mail forwarded through LiveJournal could be signed with a third. This way, e-mail providers that end up blocking one type of message would not automatically block them all.
- Less e-mail caught incorrectly by spam filters.
- More reliable message delivery results in a lower volume of Support Requests and more satisfied users.
- Lowered chance of phishing or other scams involving LiveJournal e-mail addresses.
- If all outgoing LiveJournal mail was signed, mail from a spoofed @livejournal.com address to another @livejournal.com mail address could be caught and not forwarded on, reducing spam for users.
- Calculation of crypto signatures for every message would increase overall processing load slightly.
- Requires some developer time to plan and implement.
