Thanks for your tip regarding the busy network.

I am using a one year old Cisco Catalyst 2960S (WS-C2960S-48TD-L) with cat6e 
cables and my network should not be overloaded as far as I know. My mailbox and 
mail proxy servers are on two different virtual machines on two different 
servers. It could be possible that it is something with the virtualization but 
my other VMs do not have any connection time outs or anything. I will keep on 
searching on the network side.

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
