Thanks for reporting this It seems to be a problem with your hostname configuration
Please can you open /etc/postfix/main.cf file , and update the hostname value to a valid hostname? Then restart postfix and check if that helps Best Yolanda ** Changed in: postfix (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/738000 Title: package bsd-mailx 8.1.2-0.20090911cvs-2ubuntu1 failed to install/upgrade: problemas de dependencias - se deja sin configurar To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/738000/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
