Shanbrom (Ipswitch) To: [email protected] Sent: Friday, February 18, 2005 7:46 AM Subject: Re: [IMail Forum] POP3 Timeout for Dial-Up Customers We used to see this a lot in the old days with FTP connections dying out on large file transfers. Most windows machines will optimize themselves for a LAN connection. When using a dial-up connection you need to adjust this. the Setting you are looking for is the MaxMTU or IP Packet Size depending on operating system. You can go to www.dslreports.com from the client machine and run the "tweak test" to determine what the optimal setting for that connection would be. For your typical dial-up it will most likely be 576. Also from that site you can grab DrTCP. Run this on the machines and just set the MaxMTU right there. Otherwise it's a search through the registry following specific paths...use the app!! It's a lot easier. � Eric S� ----- Original Message ----- From: Bryan E.
