Return Mail

[PHPGuru2]

I have a simple mailing list script that sends newsletter to around 600 subscribers.
However, half of the e-mails actually come back with an error. The error messages said that the e-mail account is not reachable.

Also for some reasons, after sending the newsletter, all of the e-mail accounts cannot be used for a while (can't send, receive, etc.)

I have checked the e-mail header and nothing seems to be wrong. The script sends a mail to each person going through the for loop.

i.e.

for($i = 0; $i < $num_of_subscribers; $i++)
{
     mail(parameters for mail() function);
}

Does anyone have any ideas of what seems to be the problem??

yep this also happens to me all the time. my emails return with "unroutable domain" error message.. is this the same error message you are getting?

No, it's actually for my client and he told me that he's getting a message like: "e-mail account not reachable".

I have asked him to ask his hosting service if they have a spam filter installed on their mail server.

Have you found any solutions for it?
