My mailserver had to change IP numbers on Monday evening here (due to a spammer on the same C-block of numbers), and it took about 36hours for those changes to spread in the DNS system on the net.
During this period, it seems that I have been unsubscribed from all Apache mailing lists. Isn't this "unsubscription period" a bit short?? Many ISPs are cut off from the rest of the Internet for periods longer than that (recently happened to TMnet users here in Malaysia). Anyone knows? Niclas
