add ability to configure smtp server

[fvanderbiest]

Currently hardcoded:

roles/georchestra/templates/extractorapp/extractorapp.properties.j2:smtpHost=localhost
roles/georchestra/templates/extractorapp/extractorapp.properties.j2:smtpPort=25
roles/georchestra/templates/ldapadmin/ldapadmin.properties.j2:smtpHost=localhost
roles/georchestra/templates/ldapadmin/ldapadmin.properties.j2:smtpPort=25

Terranis might be interested in using sendgrid instead.

Delivering your transactional and marketing email through one reliable platform.

Well, that looks interesting :)

But easily doable via a variable for host/port...

Usually, i have nullmailer (or msmtpd) running on localhost:25 that forwards the mail via a smarthost, maybe that can be considered too.

[fvanderbiest]

We did not succeed having nullmailer or msmtpd listen to localhost:25, so we installed exim4 ...

[landryb]

nullmailer just needs to be installed and running, and you put the SMTP smarthost in /etc/nullmailer/remotes.

okay, that's weird ...
