If you have individual email accounts at the provider, you can use 
fetchmail or getmail to connect to those mailboxes, download via POP and 
redistribute into your LAN system.

In general, smtp mail expects the recipient host to always be on line. 
If you are expecting direct delivery to a mostly-offline host, you need 
to arrange for some better connected server to handle your domain with a 
DNS MX record and queue the messages for you.  Then you need to schedule 
sendmail runs to connect to this host and issue the ETRN command which 
tells it to delivery your queue.
