 From http://www.voip-info.org/wiki-Asterisk+config+voicemail.conf:

format
The format setting selects audio file format(s) to use when storing 
voice mail messages. The value is a string defining the audio format(s) 
of the message file. The default format string is wav49|gsm|wav, meaning 
that Asterisk will save the voicemail message in all three supported 
formats. When emailing the attachment, however, it will send only the 
first of the formats defined here. What the value of saving in more than 
one format is, I don't know.

     * wav49: In this format, the file size will be small, the quality 
good, and it's a good choice for sending voicemail messages in email. 
The file will have a .wav extension, which all Windows users should have 
no problems with, and users on other platforms should also be able to 
easily play these sound files.
     * gsm: Voicemail saved in this format will have about the same file 
size and same audio quality as wav49. It may be less well supported by 
client operating systems if sent to users in email, however.
     * wav: This is an uncompressed sound format, so the file size is 
very large. Not recommended.
     * g723sf: The sample voicemail.conf file has this option commented 
out. If you try to activate it, you will find that it doesn't work.

So I don't think you can use mp3 or au format here...
