I am following this Ubuntu tutorial for installing postfix onto my server: https://help.ubuntu.com/community/PostfixBasicSetupHowto
Everything is OK until I get the sending a test email. I copy and paste the suggested text, and then press enter to get to a new line so that I can enter the
. on a new line, per the instructions. After that I keep getting the following error:
421 4.3.0 collect: Cannot write ./dfp79Kv5DF023853 (bfcommit, uid=0, gid=111): N o such file or directory
I have no idea what's going on.
