BACKUP POP SERVER

[Jhun Hubac]

Hi!

Is there a way that I can back-up my pop server? I'm using qmail for my two
servers (both have SMTP & POP3 service).
No problem of having redundant SMTP servers but it seems that the MUA
(clients) are polling on only 1 of the two servers.  I'm using NIS/NFS to
distribute information between the two, so their home directories are on a
different LINUX machine and the accounts are based on a NIS master.  Is
there a work-around for this?
