I have opened a
tmux screen and started my newsletter. It uses the
mail() php function in order to send the emails to 500,000 destinations. It should take normally no more than a day to do so.
However, I've upgraded my VPS and had to reset all my data and settings, so now I'm trying to send mail again using the same method as before (installed
sendmail, etc) and now I'm getting a
deferred connection timed out on the log files at
I tried scanning my ports to check if they're open; yes they are, I did a
telnet localhost 25 and it worked, however, I tried for example
telnet smtp.gmail.com 25 and it tries to establish a connection but fails, returning a timed out error.
I'm using the Ultimate plan of GoDaddy's servers Linux Ubuntu 14.04.
Thanks for your answers.
