set spellabsoluteaddresses= { on | off}

When this command is set to off, the spell checker ignores absolute URL’s (tokens starting with http://, https://, file://, ftp://, and mailto:), absolute file paths (tokens that begin with /, \\, or X:\), and e-mail addresses (tokens that contain a @ and a .). When set to on, the spell checker will flag those tokens as misspellings. The default is off.
