Sendmail on RH8

[Jason Dale]

Hi All:   Question #1   I am in the process of transferring mail server functionality to my new RH 8 machine , and everything seems to be working just fine. However , I need to find a way to 'test' the new mail server , without changing the MX record's IP address on our ISP's DNS servers. Is there a command I can use in Linux  to send a mail message from one Linux server to a specific account on another Linux server , referenced by IP address rather than by DNS lookup ? bear in mind that both of these Linux servers are on the same LAN   Question #2   Sendmail queues all of it's incoming mail for an account into one large account file in /var/spool/mail. Is there a way I can break these large files down into smaller message sized chunks so that they can be delivered to their recipients' computers individually ? ( naturally , the user must be logged on and must be requesting mail from the server )   Regards , Jason
