Decreased, probably, but nowhere near disappeared. > The growth of sending per-recipient tailored messages seemed to be the cause. Only in higher-end mailing list managers. The main advantages of avoiding multiple recipients is the ability to use VERP for automated bounce handling and, to a slightly lesser degree, customized URLs for list management. If I send mail from my MUA to two recipients at the same domain, or use any of a number of less powerful MLMs, they'll probably use multiple recipients for a single message. > > If my impression is wrong, is there any useful (and accurate) > characterization we can make of different types of SMTP (relaying) usage > patterns and their popularity? > Cheers, Steve
