[Typo3] Direct Mail phpcron invocation from Internet

[Mark Gillingham]

As I understand it, the dmailerd.phpcron script is meant to be called by 
the local cron each minute or so to check if there is mail to be sent 
and to send it if there is. It calls functions that send mail in batches 
of 50.

I would like to modify dmailerd.phpcron so that I could call it from 
another computer on the Internet--one that has cron available to me. In 
my naivety, I thought I could simply remove the the first line (bang 
line: #!/usr/bin/php -q) of the script, change its extension, and call 
it with wget. There must be more to it.

I would appreciate help pointing me in the right direction.
