If I send a mail to "user@localhost" it works, if I send it to "user" it does not get delivered: ----- The following addresses had permanent fatal errors ----- user@@localhost.localdomain (reason: system config error)
Heh, I remember several people including Alan advocating keeping "localhost.localdomain" because sendmail and other things would break without it.
Fixed in the sendmail-8.11.3-1 rpm I will put into rawhide today. Thanks for the bug-report, Florian La Roche
