VM2.0.2 Ask a question about this product - not sending an email

[PaulT]

I am using Joomla version 2.5.1 and VM2.0.2
In a Product Details page if I click on the "Ask a question about this product" button then fill out the form and submit,  it says it has sent the email successfully but I never get it.
I have tested a Joomla contact form and that sends out emails to me correctly.
VirtueMart is set to work as Catalog only on this site. Joomla Global setting are set to send mail via PHP Mailer.

Does this work for anyone else or are there any others having this problem?
I have tested this with the 3 basic Templates supplied with Joomla and the problem is the same with each so it doesn't seem to be a Template based issue.

Update 6 March 2012.
It would seem that this issue is not actually a VirtueMart bug as I was able to get it to work on a different server.
I haven't isolated why it is do it on the original server as yet but it seems to be related to permissions.
