[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.


hier is some information of .conf file
part of extensions.conf

; Voicemail Configuration

; NOTE: Asterisk has to edit this file to change a user’s password. This does
; note currently work with the "#include " directive for Asterisk
; configuration files. Do not use it with this configuration file.

; Default formats for writing Voicemail
; 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.
; Who the e-mail notification should appear to come from
; Should the email contain the voicemail as an attachment
; Maximum number of messages per folder. If not specified, a default value
; (100) is used. Maximum value for this option is 9999.
; Maximum length of a voicemail message in seconds
; Minimum length of a voicemail message in seconds for the message to be kept
; The default is no minimum.
; Maximum length of greetings in seconds
; How many miliseconds to skip forward/back when rew/ff in message playback
; How many seconds of silence before we end the recording
; Silence threshold (what we consider silence, the lower, the more sensitive)
; Max number of failed login attempts
; If you need to have an external program, i.e. /usr/bin/myapp called when a
; voicemail is left, delivered, or your voicemailbox is checked, uncomment
; this:
; If you need to have an external program, i.e. /usr/bin/myapp called when a
; voicemail password is changed, uncomment this:
; For the directory, you can override the intro file if you want
; The character set for voicemail messages can be specified here
; The ADSI feature descriptor number to download to
; The ADSI security lock code
; The ADSI voicemail application version number.
; Skip the “[PBX]:” string from the message title
; Change the From: string
fromstring=The Asterisk PBX
; Permit finding entries for forward/compose from the directory
; Change the from, body and/or subject, variables:
; Note: The emailbody config row can only be up to 512 characters due to a
; limitation in the Asterisk configuration subsystem.
;emailsubject=[PBX]: New message ${VM_MSGNUM} in mailbox ${VM_MAILBOX}
emailsubject=[PBX]: New message in mailbox
; The following definition is very close to the default, but the default shows
; just the CIDNAME, if it is not null, otherise just the CIDNUM, or “an unknown
; caller”, if they are both null.
;emailbody=Dear ${VM_NAME}:\n\n\tjust wanted to let you know you were just left a ${VM_DUR} long message (number ${VM_MSGNUM})\nin mailbox ${VM_MAILBOX} from ${VM_CALLERID}, on ${VM_DATE}, so you might\nwant to check it when you get a chance. Thanks!\n\n\t\t\t\t–Asterisk\n
emailbody=Dear bing just let u know
; You can also change the Pager From: string, the pager body and/or subject.
; The above defined variables also can be used here
;pagerfromstring=The Asterisk PBX
;pagersubject=New VM
;pagerbody=New ${VM_DUR} long msg in box ${VM_MAILBOX}\nfrom ${VM_CALLERID}, on ${VM_DATE}
; Set the date format on outgoing mails. Valid arguments can be found on the

; You can override the default program to send e-mail if you wish, too
;mailcmd=/usr/sbin/sendmail -t
; Users may be located in different timezones, or may have different
; message announcements for their introductory message when they enter
; the voicemail system. Set the message and the timezone each user
; hears here. Set the user into one of these zones with the tz= attribute
; in the options field of the mailbox. Of course, language substitution
; still applies here so you may have several directory trees that have
; alternate language choices.
; Look in /usr/share/zoneinfo/ for names of timezones.
; Look at the manual page for strftime for a quick tutorial on how the
; variable substitution is done on the values below.
; Supported values:
; ‘filename’ filename of a soundfile (single ticks around the filename
; required)
; ${VAR} variable substitution
; A or a Day of week (Saturday, Sunday, …)

; Each mailbox is listed in the form =,,,<pager_email>,
; if the e-mail is specified, a message will be sent when a message is

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?
