To clarify, you are running a webmail service, which connects to 
imapproxy, which connects to NGinX, and all is well with the world.  Did 
this also work with Perdition?  I'm concerned about proxies within 
proxies and the load that may cause.  But if Perdition has a high 
per-connection overhead, placing imapproxy in front of it (on an 
alternate port) may reduce the load.  I am leaning towards Perdition 
because it seemed a simpler setup (that might an illusion created by the 
lack of documentation), and because of it's support for manage SIEVE.

Regarding SIEVE, support for it may be limited.  Since Exchange does 
not support SIEVE, we might not offer it except in special cases.  As of 
this moment, only a couple dozen people have discovered clients that 
support it, and we have not rolled out a general SIEVE editor.  I am 
interested in any back-end agnostic SIEVE servers.  Something that would 
run on the proxy machines, and deliver email to the correct folder on 
the back-end server, vacation respond, etc.
