We want to send mail, configure exim4 from the console " sudo echo 'My Test Text' | mail -s Testmail name@gmail.com " works. When I configure it from the koha /etc/koha/sites/unaj-test/koha-conf.xml and/or from the web Home › Administration › SMTP servers , both gmail and the institutional mail of the university, does not send mail
This sounds like a support request rather than a bug. Questions about Koha should be asked on the Koha mailing list (http://koha-community.org/support/koha-mailing-lists/) or in the #koha IRC channel (http://koha-community.org/get-involved/irc/). Hopefully you've already seen the Koha documentation: http://koha-community.org/documentation/ You can also find options for paid support here: https://koha-community.org/support/
