    hi guys,

    I have a customer who just remade his site and sent out an email to roughly 1500 recipients, all in the to: field :)

    most of the registered users entered fake addresses, so I ended up having 5000 mails in the queue and 800 emails from the maildaemon telling me that the mails could not be delivered.

    now I have a lot of questions:

    a) how do you handle this? he sended using sendmail, which means that the bounces and maildeamon messages came back to me... can I still have him use sendmail and getting all that feedbac kback to his mail account?

    If not I'll have him use smtp

    b) how does a newsletter tool send its messages? wouldn't it be more elegant to send the mail to himself and put all recipients in the BCC field?

    c) how exactly would the server go about if he were to use b) ? I mean are there less connections made?

    thx for any advice...

    Your client must set the Return-Path header in his newsletter so that mails are returned to that email address if there are any errors.

    ok, but what about the to / bcc question? does it matter which one is used in terms of connections/resources/etc ?

    Yes, of course, because otherwise every recipient can see who else got that newsletter...

    thx - still I am curious about how "professional" newsletter tools send their mails as I have a client who had 4000 clients in his newsletter and around 800 of those emaisl came back as undeliverable, I imposed a sending max. recipients of 100 so he has to send his newsletter in portions of 100 and told him to sort his database as I wil not tolerate him sending again to that unmodified database...

    any hints on more tips? maybe a link to a good newsletter sending script or just hints how he should build his newsletter tools?

    We're using Mailgust, but the project is dead now (although we're very satisfied with it). It uses procmail recipes to handle bounced messages.

    can you send me your version of mailgust? I can only find older versions for download like 1.8 1.9 but on some sites they mention RC 2.2 or so...

    A client needed to do this, and I got MailWorks Professional (the cleint paid for it)

    It's working really nice, and till now no problems sending the newsletter to over 4000 recipients.

    Mailgust uses its own license which doesn't allow me to distribute it... :(
