I've just started to use the nationality field in sailwave and have turned on the 'use hyperlink to flag' option. For individuals who've yet to be assigned a nationality I assigned the blank flag which has a file name of three 'X's. However if I send a (html) result sheet or the sailwave file (as an attachment) it gets blocked as porn by various mail filters (both my desptach system and the recipient's). Can the blank flag be named as something else (e.g. ZZZ.jpg)?
