Question
Outbound mail (SMTP port 25) seems to be blocked by your network | Mail in a Box
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.”
Please help.

Just another quick update. I am running three droplets (one relatively large one) and ran into the same with a new small droplet we wanted to use internally. (roughly 5 email accounts) I created a support ticket and the support staff told me that they are unable to lift this restriction for my account… Instead they suggested to use a different port or an external API.
I think this restriction should be highlighted better on the page where you choose a droplet.
Best regards,
Jan
