Before that message always appear warning: problem talking to server 127.0.0.1:7777. I made some tests, my mail server is in a virtual machine, I restore before upgrade and works well, update again and appear the problem, so I think is something with las update

Thanks

It's a bug of iRedAPD-4.0 to 4.2. The new 4.3 release fixes it:
