Issues with mail sending
Q: Email messages not getting out of the openmeetings server
A: If you change mail.smtp.port from the default (25) you may have to add a permission for your port to the catalina securty policy e.g.
Add the following section to ${OM_HOME}/conf/catalina.policy.
// Permissions for jakarta mail
grant {
permission java.net.SocketPermission
"SMTPHOST:SMTPPORT", "connect,resolve";
};
