I work as one of a support team and have just had a query from one of our list 
owners. 

They have several recipients use Macs (OSx10.4.9) and Mac Mail to receive 
the HTML digest. It formats without problems but when the users come to 
click on the actual message links, it attempts to tried to open it as a file on 
the local computer rather than linking to the actual message archive. 

I've tried this on Thunderbird and Outlook without any issues (although my 
GMail account came up blank when it opened the message). 

We use Listserv 14.8. 

Does anybody have an idea why this is happening and what we can do to 
either work around the issue or fix it?

Thanks,
