EasyBlog email posting not working

Hello,

I'm trying to set up blog posts via email but cannot seem to get it working...

My IT team have set up cron jobs to run every 5 minutes and I have entered in the info they have given me into EasyBlog's Remote Publishing settings (see attached for screen shot).

When I click 'Run' I am advised that the connection is working... but I've tested sending emails to the designated intranet email address and nothing is appearing either on our website's frontend nor in the backend interface.

Sadly I cannot supply you with access details to our site but if you could offer me some advice as to why this may not be working/any settings I haven't configured correctly I'd be highly appreciative.

Thanks!
