    I'm trying to send through the Mac terminal:

    date | mail -s testing

    In mail.log I get the following error:

    "Jul 19 10:19:17 oris-imac.home postfix/error[707]: 165009630728: to=<>, relay=none, delay=31, delays=0.61/31/0/0, dsn=4.4.3, status=deferred (delivery temporarily suspended: Host or domain name not found. Name service error for type=MX: Host not found, try again)
    Jul 19 10:19:46 oris-imac.home postfix/master[682]: master exit time has arrived"

    I looked for a solution online but couldn't find any one that was useful for me, but I guess it's a DNS issue.

    Anyone know what can I do to solve this?

    Where did you look? What have you tried? Looks like a DNS problem but could be anything.

    Info and things to do and check here and here. Post some output of the commands you ran.

    While I'm testing the points you brought up (Thanks!), I'll add that I changed system preferences -> network -> advanced -> DNS to google's public DNS server and it now works.

    Anything I need to do to make it work without it?
