We know you've been waiting for an update on notifications, so we wanted to let you know what's going on instead of holding off until the next newsletter.
LiveJournal has been placed on a spam-block list by an external service used by several email providers. As a result, notifications that are ordinarily sent via email providers that use this spam-blocking service (such as Yahoo!) are not being delivered. Unfortunately, we don't have direct control over this list and cannot simply remove ourselves. Please note that this issue has nothing to do with any service or feature on LiveJournal (such as Games).
We're working very hard to get LiveJournal removed from this spam-block list. This involves widescale efforts to eliminate the root cause of the issue (e.g., certain spammers use external email to spread spam links to LiveJournal). To this end, we're researching several ways to identify legitimate LiveJournal accounts and messages, so we're not as vulnerable to being blocked in the future.
Until this issue is resolved, we suggest you use LiveJournal's internal messaging system (the Inbox) to receive notifications. You may also be able to receive notifications by IM, depending on the client you use (read this FAQ for more details). To update your settings, visit the Notifications tab and select the Inbox option (you can also try the IM option) for all your important notifications. You can then check your Inbox to read your comments and notifications.
We're very sorry that this issue has gone on for so long. Like you, we depend on our notifications. We'll keep you posted on further developments right here in news. We sincerely appreciate your patience and understanding while we try to resolve this matter.
