I’ve checked Piwik and the Ubuntu Server installation but I am not finding the reason for this issue, run Piwik for more than a year (with about the same configuration, and a new installation) The rest of the server is running fine apart from this issue. Email dns ftp websites etc. I’ve tried mail settings in Piwik they did not result in a solution. Network name settings en php settings are the same as the former installation.
Piwik is using the correct email address, only the lookup for links ends up at localhost and sent from localhost instead of the fqdn
This is not a mayor issue but would be nice and easier if resolved.
