Hello I just installed nagios 3.0 on Ubuntu 7.10 and am having troubles with the e-mail notifications. The document I used said to install mailx in order to receive mail notifications. Everything is up an running great except for the mail notifications. I tried a test mail and when I checked my mail by checking mail it gave me a unroutable address error and when I send to my hotmail account it says mailing to remote domains not supported. Any ideas?
