I got a new VPS setup and I'm wondering why I can't send emails to yahoo and gmail. Here's the error in /var/log/maillog:
00:43:00 mylamp sendmail: o45Gh0nc032505: to=, ctladdr= (48/48), delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=120405, relay=alt4.gmail-smtp-in.l.google.com. [18.104.22.168], dsn=4.0.0, stat=Deferred: Connection refused by alt4.gmail-smtp-in.l.google.com
What seems to be the problem?
