    452 4.5.3 Too many recipients specified

    Hi,

    When I try sending an email to many people, the follwing message is returned. My Q. is - did it reach all the recipients or not?

    Also, is it from my ISP or where is the problem's source?
    How can I determine he total no. of permitted users?

    Note I have replaced the actual SMTP emails with placeholder ones to maintain confidentiality.

    Thanks,

    m.q.

    To answer your first question, obviously not all as you have received at least one failure notification. As to exactly how many - who knows? A mail server that has rejected the mail because of the size of the header may or may not have sent you a notification.

    Where did the message come from? View the header for that information.
    Are you using a local mail server (such as Exchange), or Outlook/Outlook Express direct to an internet account such as Hotmail?
    How many recipients have you specified? - apart from being considered 'bad manners', many mail servers will simply reject mail with too many on the basis it could be spam. The maximum number of permitted addresses in the To: header could vary from server to server - I believe ours is set to parse only the first 50 for a local address.

    In addition to Leif's remarks, this was a known issue on Exchange servers at one point which I believe has since been resolved. What mail protocol are you using - IMAP, POP3, or something else?

    Hmmm, ok.

    This email was sent from my PC via a normal dial-up connection to my ISP.
    I use POP3 to receive my mail, but SMTP to send outgoing mail.

    I could try sending to 40 recipients at a time, but my list has a thousand people & I will go crazy!
    Is there not a better way to do this? My email also includes an attachment.

    Thanks,

    m.q.

    The better way would be to investigate some list server software or service that is designed for large mailing lists. The key there is to avoid ones that are recognized as spam generators.

    I can't personally recommend any list server software, but I can suggest to check the rules file for SpamAssassin to see the ones that will get junked by that particular spam filter:
