NO NO NO as I stated above it is sendEmail.

Just to make absolutely clear how to use sendEmail, here is the snippet
of my C++ code that sets up and calls sendEmail:-

{
 strcpy(SendEmailBuf, "sendEmail -q -f ");
 strdncat(SendEmailBuf, Settings.ReturnEmailFrom(), SENDEMAIL_BUF_LEN);
 strdncat(SendEmailBuf, (char *)" -t ", SENDEMAIL_BUF_LEN);
 strdncat(SendEmailBuf, Settings.ReturnEmailTo(), SENDEMAIL_BUF_LEN);
 strdncat(SendEmailBuf, (char *)" -u \"", SENDEMAIL_BUF_LEN);
 strdncat(SendEmailBuf, Dates.ReturnReminderTextPointer(),
SENDEMAIL_BUF_LEN);
 strdncat(SendEmailBuf, (char *)"\"", SENDEMAIL_BUF_LEN);

 strdncat(SendEmailBuf, (char *)" -m Repeating reminder",
SENDEMAIL_BUF_LEN);

 system(SendEmailBuf);
}

Further, I have a section in my Ubuntu server 14.04 setup notes that
suggests:-
Compile the reminder program.
Move DFReminder to /usr/local/bin/
Restore the entries to crontab
Might need to alter
/etc/hosts
from
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
to
::1     ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
in order to keep dfreminder working

which I think was a suggestion by Karl after I asked a question on
ubuntu-users.

I also seem to remember having to add localhost to the mynetworks line
in the postfix/main.cf to get postfix to accept reminder emails, from
the program which runs on the same server kicked off every night by
crontab.

That, I think, is just about all that I can say on the subject.

Bye for now.
