Hi,

I'm wanting to unblock port 25 on my Fibre line for a test mailserver for my homelab I contacted Skinny support and they've said "Our backend team has come back and advised Port25 is unblocked on the network. There is nothing much we can do on our end."

But when I test from a remote connection 25 is still blocked and requests aren't even hitting the firewall.

I see that Spark has a form you can fill out to remove port blocks does anyone know if Skinny has the same?

Thanks.

Are you on a static IP ?

I'd assume you are....

IIRC Sparks port 25 blocking is an outbound block to prevent spam, In order to make this accessible externally you would need to port forward port 25 on your router. (Don't do this, Save yourself the hassle and just use gmail / m365 etc).

I do not believe that Skinny offers the ability for customers to opt out of this filtering.

No, Not using a static at the moment. I've read this can hurt sender reputation. I was hoping it would not affect me too much as I'm just using this as a learning tool not for production purposes.

The plan would be to migrate to M365 later.

No static IP on Skinny = no port 25 unblock.

If you wanted more advanced features you'll need to go with a more advanced provider. Quic (https://quic.nz) are not too much more price wise and may work for you - there are referral codes in the Quic thread on here to get a free install.

Else, depending on your requirements you could always fire up an Oracle Always Free VM (or any other providers offering) and test via that.

Thanks. Looks like I'll need to find a new ISP once my contract is finished.

Not heard of Quic. I'll take a look. Thanks.

Migrate to office 365 straight away, mucking around with on-prem mail servers is so last decade make it someone else’s problem.

If you do ever set up your own SMTP server, you do NOT want it to be sending emails out directly to other SMTP servers. These days, emails arriving from unknown SMTP servers are viewed as spambots and will be blocked and will get your IP address onto many blocklists. I have been running my own SMTP server since I had my first 128 kbit/s ADSL connection and I when I accidentally configured it to send directly, I rapidly discovered how bad an idea that was. What you need to do is have a recognised SMTP server relay your outbound emails for you. I am on 2Degrees, and they have an SMTP server that does this for me (free for use by their customers). But you can also buy this sort of service for small annual fees from a number of services. I have my backup MX servers with dynu.com and they offer SMTP relay for a very decent price. If you run your own inbound SMTP server as I do, then you will also need to pay someone for backup MX service so that during any period your SMTP server is unavailable, the emails will be received by one of the backup MX servers. Backup MX service is also normally very cheap, unless you are having a huge volume of emails.

Yeah, avoid running mail services from home these days, only takes one little "oops" and the whole thing goes nuclear.

I ran my own mail server for quite some time, and while only had one major "oops", it took a long time to recover from - domain was blacklisted all over the place, ISP effectively cut me off.... reputation took a hit.

Let it be someone elses headache.

I ran on-prem exchange up until 2019. Eventually decided the hassle of patching / power / open ports was not worth it. Easier to pay Microsoft $9 per month for business basic which gets me full exchange with domain, 1TB one drive and Sharepoint Space

Its not just exchange you need AD as well and that has to be patched and maintained too.
