$smtp->auth('CRAM-MD5', '$ServerAccount', '$ServerPwd');
I suspect you do not want single quotes around your variables. They prevent variable interpolation. Try this: 
$smtp->auth('CRAM-MD5', $ServerAccount, $ServerPwd);

perlcritic can warn you of this common type of error: 

$ perlcritic -1 --verbose 6 893592.pl
String *may* require interpolation at line 10, near ''CRAM-MD5', '$Ser
+verAccount', '$ServerPwd''.  (Severity: 1)
