[HELP] Using a simple email client instead of sendmail

I would like for our Asterisk users to receive their voicemail messages via email, but I would prefer not to have sendmail running on my system. It seems to me that a mail tranfser agent (MTA) like sendmail is overkill when I can simply use an email client like sendEmail. Further, sendemail seems like something of a pain to configure, where a simple email client requires almost no configuration at all.

The problem is, I don’t know how to configure Asterisk to use a more simple client like sendEmail. I have been experimenting with the “mailcmd” setting in voicemail.conf, but not having much luck.

Has anyone tried this? Can anyone tell me what command Asterisk actually attempts if I set “mailcmd” to “/usr/local/bin/sendEmail -f joe@greatco.com -s mail.qwest.com -t”?


google ssmtp

You can install it and run the ssmtp-config command and it will run when sendmail is called.


Yeah, but if you just want to use sendmail as a client and not a mail server, there’s not much to configure, you just need to tell sendmail which mail server you do want to use.

Just edit your /etc/mail/sendmail.mc file by uncommenting the SMART_HOST statement, pointing it to the mail server that you want to use, and then process the file using make, and then restart sendmail.

Just edit your /etc/mail/sendmail.mc file to tell sendmail what mail server you want to use.


Process sendmail.mc file and Restart sendmail

cd /etc/mail
/etc/init.d/sendmail restart

Thanks for the tip. That is exactly what I was looking for. Unfortunately, I think I still have something configured incorrectly.

My guess is that I need to pass some sort of authentication to the email server I want to use. Note that I DO NOT need to pass any authentication if I use an email client like sendEmail or Evolution. The reason I think I might need it when using sendmail is in the mail log below where it says:

stat=User unknown

The name of the email server is mail.allguardpc.com. If you see anything in this mail.log file that might give you a clue, please let me know.

Well ok, maybe a few more things…
Here is how you can enable authentication.

Uncomment the two lines in your sendmail.mc



Add the following line to your sendmail.mc:

FEATURE(`authinfo',`hash -o /etc/mail/authinfo.db')dnl

Regenerate the sendmail.cf file by running make

cd /etc/mail

Create a file called /etc/mail/authinfo, add the following line (see AUTH related at sendmail.org/~ca/email/sm-812.html#812AUTH for more details):

AuthInfo:mail.allguardpc.com "U:<username>" "P:<password>" "M:PLAIN"
AuthInfo: "U:<username>" "P:<password>" "M:PLAIN"

Create the authinfo database by running the command

makemap hash /etc/mail/authinfo.db < authinfo

Restart sendmail

/etc/init.d/sendmail restart
