Any free hosting provider that allows port 25 ?

I wanted to deploy a stalwart server but port 25 is blocked on google cloud VM.

I also can't find a single hosting provider that I can use to host this server. I want a free instance no matter what, even 256mb of ram would work as long as its free.

Willing to pay once I exceed the usage of free tier.

I am not aware of any free hosting providers that allow port 25 access. You can try with Hetzner, it is paid but they'll give you port 25 access after a few weeks of having an account with them.

Hi @mdecimus , Since port 25 is used to receive mail, Can we just setup stalwart for sending mail on some other port.

This would allow me to send basic mail (forgot password, confirmation mail & other marketing stuff) from my own server without having the limit of 1000 mails / month that is given by services like sendgrid.

Could you provide the documentation for setting up stalwart for only sending mail. I use skiff for receiving mail for my custom domain.

During installation, The server should print which ports are blocked and which are working in the terminal, Also telling what is blocked like

Port 25 Blocked : Email cannot be received.

Where alternative ports can be used, Server should configure it automatically or provide the option for it.

SMTP transactions must be done on port 25. If your VPS is blocking outgoing SMTP connections then you only alternative is to configure a relay hosts.

contabo.com vps allow it, but
They monitor excessive sending of emails and you will receive a warning if you exceed the limits

@wakaztahir
Google Does NOT block incoming port 25.
They block outgoing port 25 for almost all of their clients though.

Most likely, you shouldn't try out any of the big providers like GCP, AWS or even the dreaded Azure as they all do the same.
It take a LOT to get whitelisted on them BTW.

Better go for something like DigitalOcean, Vultr, Linode etc.

cool, so I could setup stalwart server to receive mail on GCP using port 25 and send using the other 4** port, I'll try that
