Moyes acknowledges Ferguson's message could make his job easier when he arrives at Manchester United.
"I knew nothing about what he was going to say but it was nice to hear it. Hopefully it will make my arrival a little bit easier," said Moyes.
"I'd give the same message to Everton fans about whoever follows me. It is really important that Everton, whoever their new manager is, welcome him like Sir Alex has done, to keep things strong at the club."
