my interpretation:

a) you have a very very bz network ... the other end cannot respond to incoming requests

   even if your network is NOT bz, eg, no collision blinking on your hubs/switches,
   you are still having network problems

b) if all of your dovecot tests is on one host  ... disconnect it from the network
   and see if dovecot's auth finishes its tasks

c) to clean up your network ...
	- use switches ... not hubs .... even inexpensive netgear switches is good enuff
	- use good 3-6' cat6e cables ... we'll assume the bldg's wiring is done to bldg specs
		- my guess, you're probably having cabling problems )
	- separate slow devices from faster devices
		eg. separate printers onto its own network with a switch
		in between printers and everybody else 
	- separate 10/100 devices from gigE devices ... do not mix them up on the same switch/hub
