SMTP Services<br />

header of every file, but based on certain indicators, selects only files that it<br />

determines are susceptible for virus scanning. Scans files by an intelligent<br />

combination of true file type scanning and exact extension name filtering.<br />

• Specified file extensions...—Manually specify the files to scan based on<br />

their extensions by clicking Specified file extensions... and then clicking the<br />

link. A Scan Specified Files by Extension window appears.<br />
