Enquiry for academic research

[Vicky Yuen]

Dear sir/madam,

Hi~ I have just come across your site, and would like to ask you one question 
about your mailing list archive. Your input will be valuable to my academic 
research.

What kind of software you have adopted to support the mailing list function? 
Is it opensource based?

It would be grateful if you could kindly help on this.

Thanks for your attention!

Cheers,
Vicky
