you do also need to make sure the "rcpthosts" and/or  
"morercpthosts.cdb" files are built on the remote server (what i call  
a "mailhub") as well... but that's only an issue when you add or  
remove domains. and in either case, there is no need to synchronize  
an entire directory structure.


the web page does explain the mechanics and has a bunch of scripts,  
but it also relies on qmail being built with my validrcptto.cdb patch  
as well... and while i (obviously) think it's better, it can be a  
little bit of a learning curve for somebody who is already used to  
some other solution (such as chkuser.)


tom, feel free to contact me off-list if you decide to try going the  
validrcptto.cdb route and want to ask questions.

Don't use Verio - we have a system right now and they keep mucking up my
startup configuration, putting crontabs back that I've deleted, and
semi-randomly restarting services (including those I've turned off) every
time  the do an OS update (they "relink" just about everything, which is
good for binaries but bad for configuration files...).  I've already
spoken to someone once, and it seems liek they're still getting the hang
of doing it on Linux (they have apparently done this for a long time with
BSD).  Probably great if you just need a {random|generic} linux box to
work with, or want all their default services running, but we're using it
for external nagios monitoring and I want nothing running that isn't
needed for that...

(I do not want to move web and email hosting for a bunch of domains).


I'm currently considering a VPS (virtual private server) solution, and 
it looks like I'll be fine with a server that provides 512MB of RAM and 
a minimal amount of disk space.  Can anyone recommend a hosting company 
that they've been happy with?


My plan is to do a full Shupp Toaster install, but leave out apache and 
SquirrelMail.  I'll use rsync from my main server to sync 
~vpopmail/domains (minus Maildir directories) so chkuser will work.  
I'll sync the appropriate files from /var/qmail/control, and add an 
smtproutes file built from the rcpthosts and morercpthosts files (it 
will just point to my server's IP).


If, over time, the VPS becomes overloaded, I should be able to pay for a 
larger resource allocation with my VPS provider, or just duplicate the 
VPS and start another instance with it's own IP and have 
equally-weighted MX records point to each.  I'd probably even host the 
VPS copy with a different provider for redundancy.

I've heard good things about Slicehost (www.slicehost.com) from friends 
but have not used them personally.
