Mail: e-mails do not reach their recipients

[CLAUDE]

Hi,

I'm using Mail on an Ibook to sent out every now and then some e-mails to my mailing list (around 600 addresses). Lately, some of the subscribers have complained not getting the mails anymore or getting them up to six times or getting a blank e-mail.

When I sent out an e-mail, I sent it to no more than 20 people at a time. Once the first mail is sent, I sent the second one and so on. I checked with the web hoster and the ISP and they confirm 'every is testing fine on their side'.
Has anyone encountered the same problem(s)? If yes, what can be done to fix it ?

Thanks

I wouldn't think this would be a problem with Mail unless its having problems communicating with the ISP's SMTP server. Who is your ISP, maybe some users that use that specific ISP could shed some more light on this problem.
