[help]question about configuration of voicemail

I followed the guide of the book “the future of voip” to configure the voicemail.conf, but it wont work . I used the sip debug in console, and saw it said:Cannot open mail:25
can someone help me to figure out where is the problem?
btw,what is the pager_email? will anybody explain?

Post your extension.conf. We cannot help without information.

your asterisk box cannot connect to your Email server “mail” or sendmail is not configured.

; WARNING:
; If you change the list of formats that you record voicemail in
; when you have mailboxes that contain messages, you MUST absolutely
; manually go through those mailboxes and convert/delete/add the
; the message files so that they appear to have been stored using
; your new format list. If you don’t do this, very unpleasant
; things may happen to your users while they are retrieving and
; manipulating their voicemail.
;
; In other words: don’t change the format list on a production system
; unless you are VERY sure that you know what you are doing and are
; prepared for the consequences.

Ithink you need a space in here

403=>75938226,bing,bxjy2002@msn.com
406=>75938226,siwen,bxjy2002@msn.com

406 => 75938226,siwen,bxjy2002@msn.com

Also if you want send mail to send your email you will need to uncomment this line

;mailcmd=/usr/sbin/sendmail -t

Most alpha Pagers are capable of recieving email that is what pager_email is for it drops the recording attachment and just tells you you have a nw voicemessage and diplays the CID info

it still wont work
can someone tell me how to configure the voicemail.conf,
and the ssmtp.conf?
