Murder frontend problem

[Major Csaba]

Hi,

Thanks for the quick answer.
I managed to get further as I realized I missed a small piece from the 
documentation. My fronted server and master update server is on the same 
machine and I didn't configure the "mupdate_*" parameter. But as I can 
see, the proxy still has to speak to mupdate when I would like to create 
a new mailbox and the auth info is necessary even if they are on the 
same host.

So, it seems to be a misundersanding of the documentation which is not 
so verbose :)
I added the mupdate_* parameters (pointing to the host itself) and it is 
working fine now.

There is one more small question: why the proxied LMTP needs to have 
"admins" permission on the backend? I thought the proxyservers setting 
is for this, but LMTP doesn't work without adding my proxy user in the 
"admins"...

Best regards,
Csaba
