I have installed OS X Mavericks on macbook pro, macbook air & iMac but I am having terrible trouble with apple Mail. I need to take all accounts online frequently OR worse I have to quit mail and restart computer. Is anyone else having problems?

I just checked to see if the update to OS X Yosemite 10.10.1 solved any of the issues outlined in my previous post, and to my dismay, nothing has changed -- all of the previous problems persist.
My iMac (8) -- it's renamed itself eight times since the recent troubleshoot with the Apple tech rep -- shows up as a shared device in Finder on my MacBook Pro, but when I click on it, I cannot establish a connection using "Connect As".  So I've attempted to connect using the menu "Go/Connect to Server...", using both (alternately) the iMac's name and IP address, to no avail.  I get a message which reads: "There was a problem connecting to the server 'Peter's iMac (8)'. This server may not exist or it is unavailable at this time.  Check the server name or IP address, check your network connection, and then try again."
Here's what I know:
The server -- Peter's iMac (8) does exist;
The server -- Peter's iMac (8) is available at this time;
The server name -- Peter's iMac (8) -- is correct, as specified in the system sharing preferences;
The server IP address is correct, as specified in the system sharing preferences;
The network connection is active when I attempt to connect.
I'm convinced the problems stem directly from the OS X Yosemite update.  None of this was ever remotely an issue in the previous OS X's -- any of them.  This is maddening!  What can be done?  Apple?? Anyone???
