I wanted to provide a webmail login for the staff at our board so I created
an XML menu that displays in the adminCP.
It was much easier to simply provide an external url for the email FAQ
but I didnt know the security involved in doing so.
This is how my admin menu is coded:

<navgroups product="vbulletin">

	<navgroup phrase="*****" permissions="*****" hr="true" displayorder="1">

		<navoption displayorder="1">
			<phrase>log_in</phrase>
			<link>http://webmail.*****.com</link>
		</navoption>

		<navoption displayorder="2">
			<phrase>faq</phrase>
			<link>http://faq.*****.com/e_mail/webmail_/index.html</link>
		</navoption>

		<navoption displayorder="3">
			<phrase>*****</phrase>
			<link>http://faq.*****.com/e_mail/setting_up_email/index.html</link>
		</navoption>

	</navgroup>

</navgroups>

~please ignore the asterisks.~

Does anyone know if there is a security risk with providing external urls within the adminCP?
