Enable programs on VM to send mail to project members

[jkeenan]

We are not yet able to send email from inside the VM. While I do not want to send a lot of email from inside the VM -- and while I don't want to receive email within the VM -- I do want the 'test-against-dev' process, once in production, to be able to send project members one email daily indicating whether it has detected the presence of a new perl-5.29 monthly dev release or not (which will be not all but one day per month).

The program I wrote to send email was /home/jkeenan/learn/perl/first-email.pl (and, on my Linode, this was indeed the first program I ever wrote to send mail that relied on the presence of sendmail and an SMTP server).

Inside the VM, I get:

$ ps auxwww | grep -i sendmail
root      658   0.0  0.2  20636 3388  -  Ss   Sat00      0:03.51 sendmail: accepting connections (sendmail)
smmsp     661   0.0  0.2  20636 3132  -  Is   Sat00      0:00.06 sendmail: Queue runner@00:30:00 for /var/spool/clientmqueue (sendmail)
jkeenan 15516   0.0  0.1  14828 2220  0  S+   20:03      0:00.00 grep -i sendmail

But on the host, I only get:

$ ps auxwww | grep -i sendmail
jkeenan 11171   0.0  0.0    6660    2528  0  S+   20:03        0:00.00 grep -i sendmail

But I myself have never set up sendmail, and I haven't had time to investigate this further.

We need an smtp relay that we can use. After we have that information, we can edit the directive

dnl define(SMART_HOST', your.isp.mail.server')
