Outgoing mail including validation email, comment notifications, and livejournal.com email redirection is currently being delayed because of a high volume of mail passing through the LiveJournal mail server.

Это я пишу к тому, чтобы постараться снизить во френдленте число недоумённых постов из серии "где мои комменты??"
Upd2: We used to have 2 email servers, even though we only needed 1. Then 1 blew up the other day, and the 1 surviving one wasn't enough to keep up with all the email and got behind.... so now we have 3 mail servers online, but that one burdened one is still catching up, sending out many-day-old mail. You'll continue to get old mail for a while, but it should catch up soon. We're going to be redoing our mail architecture, though, after seeing how easily our existing setup died. (отсюда)
