Hi, I have been using Mail in a Box for a while now and it was all working fine but suddenly it stopped working.
I checked the “System Check” section on Mail in a Box’s Admin Panel and it says “Outbound mail (SMTP port 25) seems to be blocked by your network. You will not be able to send any mail. Many residential networks block port 25 to prevent hijacked machines from being able to send spam. A quick connection test to Google’s mail server on port 25 failed.”
