  • Default SMPT Virtual Server remote hosts dropping some mails but not all

    I have a server that is running IIS 6.0 on a Windows 2003 server. This running the Default SMTP virtual server for mailing.

    This sends out automated invoices, but for some reason, some get through others are rejected.

    On checking the event logs. It says that the remote hosts drops the connection. Cannot find anything useful on teh net that doesnt apply to exchange server.

    Some sites have mentioned that changing from Ehlo to helo may fix it. But there doesnt appear to be this option under ISS.

    Anyone know of anything to do this or any ideas how to fix?.
