static IPs are available with TekSavvy Fibre
TekSavvy recently started offering Internet over Bell's fibre in the GTA. The great news is that static IPs are available over fibre as they are now over DSL. Apparently, TekSavvy uses PPPoE for the fibre connections. Also, I have been using a static /56 subnet from TekSavvy for years at no additional cost. They are saying that I can migrate my current static /56 subnet from DSL to fibre. I am extremely happy with that. They have been also providing one static /30 IPv4 subnet per residential customer at the cost of $5/month. I don't know if this is still the case now.

I'm on Rogers and while the IPv4 address is DHCP, it changes so seldom, it's virtually static. They also provide a host name, based on modem and router MAC addresses, that doesn't change unless you change the hardware. As for the IPv6 prefix not changing, that's normal. A "DUID" is used to identify the client and unless it changes, the same prefix should be obtained. I expect Teksavvy is managing their own IPv6, as Bell doesn't yet offer it to consumers, as far as I know. This means you should get the same prefix, no matter how you connect. I've had the same prefix on Rogers for over 5 years, even though I've replaced both my cable modem and firewall (pfSense) computer.
do they still block inbound/outbound SMTP? On Sat, Jun 8, 2024 at 5:24 PM James Knott via talk <talk@gtalug.org> wrote:

I cannot verify this, but it's to be expected that residential connections would block this feature. Otherwise, the ISP risks getting their IP range blocked by spam block lists should one customer become hacked, or otherwise misbehave. They'd be crazy to allow the possibility of that happening (IMHO). rb

Large mail providers such as Gmail, outlook.com and yahoo.com already know if an email comes from a DHCP pool and if so they deliver such mail pieces straight to the recipient's spam folder. If your public IP address is in a DHCP pool, try checking its reputation and you will see why it is not a good idea to host an email server on an IP address from a DHCP pool: https://mxtoolbox.com/blacklists.aspx https://multirbl.valli.org/lookup/

What about IPv6? Rogers and Teksavvy hand out a /56 prefix. That's 2^72 addresses that are not DHCPv6, unless you make them that. Normally, you'd use SLAAC and I don't know if those companies would have a list of subscriber prefixes.

Gmail requires that the IP address of a mail server resolves back to the domain name specified in the SPF record of the mail domain. This is so for both IPv4 and IPv6. TekSavvy's easily agreed to make a rDNS entry in their DNS servers for my static IPv4 address. For the IPv6 address of my mail server, they kept saying they wouldn't do it for many years. But they agreed to do it last year, possibly as an exception. So now I can send outgoing mail using both IPv4 and IPv6 and the mail is delivered to inboxes, not to spam folders. Those who consider setting up a mail server at home: setting up an SMTP server is easy, but making sure that the email goes to inboxes and not to spam is a really, really arduous job.

I just did a port scan with www.grc.com and port 465, SMTPS gets through, but 25 didn't.

Still, you want to use 465, which is SMTPS.
What if some other smtpd tries to deliver on 25 though? 465 would be good for the MUA (i.e. Thunderbird), but it doesn't seem reliable to depend on all possible other smtpds to connect that way. (If I understand things correctly.) rb

I provide StartTLS on port 25, and my observation is that most MTAs these days prefer SMTP over StartTLS rather than sending email over insecure SMTP. I do allow insecure SMTP for fringe cases of some super old MTAs. And yes, I provide SMTPS on port 465 too.

I believe there are two topics here, incoming and outgoing Even if the ISP allows incoming on port 25, they are more likely to block outgoing. In that case relaying your outgoing email through a third party could be the only option, I have been doing this for ages by using an account on mxroute.com, and I am sure there are other email providers that can be used as well.

Right. The IP Reputation is the king in outgoing mail delivery. If your IP address comes from your provider's DHCP pool, don't bother. Your emails from that IP address are going to end up in the spam folder. Basically, for outgoing emails the choice is to either use a third party or have a static IP address.

What are "end user services"? Are you talking about a block by the ISP or a block in your house (i.e. the Bell Modem or your router (if any) or your computer?

Try setting up your own mail server with an address from the DHCP pool. Most or all of mail sent from such IP address will go straight to the recipient's Spam folder.

I used to run an IMAP server, but never SMTP. I had no problem with IMAP.
