From the Stalker web site / SIMS instructions: "Relay Restrictions and Mobile Users If some of your users travel a lot, they may use various ISP to connect to the Internet, and as a result they can connect to you Server from various IP addresses. If those users use your Server as an SMTP mail relay to which they submit all outgoing messages, Relay Restrictions will not allow them to send messages when their IP addresses are not listed in the Client Hosts list. To avoid this problem, the POP module of the Server remembers all IP addresses used to make successful connections to a user mailbox. For 30 seconds those IP addresses are considered to be Client Host addresses, so mobile users can send mail via your Server right AFTER they have checked their mailboxes. The 30 seconds expiration time is used because of the "dynamic IP address" policies of most ISPs: when a user disconnects from the ISP modems, and some other user connects to the Internet via the same ISP, the same IP address can be assigned to the new user: ISP assigns the first available IP address from the pool they have for their dial-up clients. Inform your users about the 30 seconds limit. They should compose all their messages off-line, then they should connect to the Internet using any ISP, check their mailbox on your Server, and only then they can send the queued outgoing messages. If they want to reply to some messages they have just retrieved from the mailbox on your Server, they should use the Get Mail command in their mailer application again, and only then they can send their replies." Of course, you can also use SMTP AUTH instead... Best wishes, Christian. -- Christian F.
