Checking email will depend upon the email service/ISP with whom you have an account. Most email hosts provide some form of Web Mail which will allow you to access your email in a web browser using your account's name and password.
To determine the MAC address of the source in the first frame, you would need to analyze the frame's header information, typically found in a network packet capture tool like Wireshark. The source MAC address is usually listed alongside the destination MAC address in the Ethernet frame header. If you have the specific frame data available, you can extract the source MAC address directly from there. If you provide more context or data, I can assist further!
Each packet carries the address of the intended recipient. Each computer has a unique address. It works rather like the postal system.

An Ethernet header is a portion of data that precedes the payload in an Ethernet frame, containing essential information for data transmission over a network. It typically includes the source and destination MAC addresses, the EtherType field to indicate the protocol used in the payload, and other control information. The header enables devices on a local area network (LAN) to identify and process the incoming frames correctly. In standard Ethernet frames, the header is usually 14 bytes long.
