Re: Huge Email Service
... think about a solution whitout NFS (cause "it's quite unforgiving").
the proxy concept takes advantage of the semi/quasi atomic POP3
operations and it performs faster then NFS does.
the POP3 client has to ask for any single message to fetch - imagine the
POP server crashes right at that moment - then the proxy allready has
transfered some messages successfully and can give a message like "no
new mails" or "system unavailable" whitout any harm to the mails that
can be fetched later.
this system relys on MailDir format.
