hiya,
yes it should appear white. if you run it via cronjob it wont be seen by anyone anyway, and if you run it yourself, its just white.
if you think you need a link back to your forum-mainpage, telle me and ill post what to edit in the file.
second issue:
you include a part or the whole email-address of the sender to make sure only the emails that you want to be posted are posted.
so if your sender is
listserv@jelsoft.com and you put $allowsender="listserv@jelsoft.com", then email from any other email will be ignored. if you put $allowsender="jelsoft.com", then any email from jelsoft would be parsed...
hope that clears it.
greets
kreftt
