Hello,

From the forum posts that I can find, imaps/pops is not supported on the  
backend of an nginx proxy, is this true? Is this a planned feature?

I ask because we have a situation where we would like to use our common  
authentication service with an outside service provider, however we will  
not be allowed to send any of our passwords to them (ie we can’t sync  
our authentication databases).

We were looking at using nginx to provide imaps to our users and  
authenticate them through our db, then proxy them to the outside  
provider using a stored ‘provider password’ for that user (ie. the user  
connects to us via imaps (or pops), we authenticate them against our  
common authentication service, then look up their provider password  
(just a random string, which they dont know) and complete the backend  
proxy connection over imaps.

In the absence of imaps on the backend side of an nginx proxy, does  
anyone have any other suggestions for setting this up?

Thanks,  
Wayde.
