How do I specify the report from e-mail address?

How do I set the from e-mail address used by the sitemap e-mail notification?

Actually, that was done in the build that is not yet available. You can change "from" email address in vbseo_sitemap_functions.php file now.
FIND:

PHP Code:

        mail($email, 
            'vBSEO Google/Yahoo Sitemap Updated', 
            $mailbody); 


REPLACE WITH:

PHP Code:

        mail($email, 
            'vBSEO Google/Yahoo Sitemap Updated', 
            $mailbody,"From: email@domain.com"); 


Perfect thanks,

I opted for:

PHP Code:

mail($email, 
            'vBSEO Google/Yahoo Sitemap Updated', 
            $mailbody,'From: '.$vboptions['webmasteremail']);
