It was impossible to me to create an account on Koha site (to contribute[0]) I tried with several usernames and different email addresses and always get this error: "Error: Failed to create your account: we were unable to send your password to your email address: {'my_mail@gmail.com': (550, 'relay not permitted')} " When trying to contact Koha's site admin I also receive almost the same error: "Unable to send mail: {'site-admin@koha.org': (550, 'relay not permitted')}" What can I do...? Regards, Pablo PS: Also there is a problem with variables on footer: "El ${plonecms} es © 2000-2009 por la ${plonefoundation} y otros." PS2: It seems some things were lost in the way to Plone, like some mailing list on: http://koha.org/support/free-support [0] http://koha.org/documentation/how-to/use-help-center
