[Mailman-Users] Subscription mail-back failure

[Jan Steinman]

I have a hosting client who is seeing intermittent failures of the  
subscription process. The user successfully fills in the subscription  
information, gets the subscription confirmation notice with the link  
and then tries to reply, and gets a bounce:

Apparently, clicking the link is working, because hundreds of  
subscriptions have succeeded. I can only assume the only ones failing  
are ones that people mail back, rather than clicking the link.

This is a fairly plain-jane installation. EcovillageNewsletter.org is  
defined as a virtual domain. I don't see where I should have  
configured anything special to enable this. Other mailing lists I host  
(also on virtual domains) )aren't having this problem.

Any clues where I should begin digging?


:::: Because the -- all which is on the table begins to address the  
big cost drivers. For example, how benefits are calculated, for  
example, is on the table. Whether or not benefits rise based upon wage  
increases or price increases. There's a series of parts of the formula  
that are being considered. And when you couple that, those different  
cost drivers, affecting those -- changing those with personal   
accounts, the idea is to get what has been promised more likely to be

sense to you? -- George W. Bush ::::
