SMTP relay settings

Just recently switched to Telus from Shaw and for some reason, there either isn't a working SMTP relay or it is blocking me.

Does anyone know what Telus Internet mail relay settings are? I tried a support call, but the person I got didn't seem to understand what SMTP was.

Here are the mail settings for Telus:

Thanks, unfortunately the standard gmail setup will actually change the outgoing email address, which is entirely what I'm trying to avoid.

Are you trying to run your own SMTP server? If yes, I do believe those may be blocked on residential accounts if the server is using port 25.


If you find a post useful, please give the author a "Like" or mark as an accepted solution if it solves your trouble. 🙂

I am running my own SMTP server, and while Shaw (and all other ISPs I've used) block port 25, they provide access to an SMTP relay server for sending mail, thus providing a safe workaround for the blocking of port 25. This is a major limitation.

Telus doesn't support servers on residential accounts.

 

You will likely need a business account to get this to work.

Yes, Telus had an open smtp relay server in the past (it is still around but no longer maintained so a huge range of newer customer IPs are now ignored/blocked from connecting) at smtp.telus.net:25  Now it mostly responds with "ESMTP server not available" if your IP is not in the dwindling list of allowed IP ranges.  If anyone still uses this beware.  It is going away and will likely stop working suddenly on you one day soon.

 

 

The gmail server indeed would only work if you were using the Telus provided email address or some other google hosted mail like gmail or google workspace for a custom domain name.

 

A workaround I have used is to sign up for smtp2go service.  Their server still requires a login to use, but it allows me to at least setup a more flexible configuration on my outbound email address for a few printers.  If you own your own domain name you can add some customizations to allow better reporting on the emails you send through their system if you can add some dns records.  There is a free tier for low volume users, but businesses may hit the usage limit for any serious usage.  For the average home user just using gmail, yahoo, hotmail/outlook etc then you would just end up connecting directly to that services outbound mail server and authenticating properly with your account.  

If you have some really old and bad equipment then running your own internal mail server that accepts unencrypted, unauthenticated mail and relays it out with higher levels of encryption may be required.  A virtual machine or little raspberry pi and a deep dive into setting up a linux server to run as a mail relay is likely required in that case.  As time marches on the Internet seems to want everything encrypted and authenticated.  No more blind trust on the email server relaying outbound mail for you.

Good day…

 

I ran into this exact problem when I switched from Shaw to Telus just over a year ago. The only solution that I found that was acceptable to me was to step up and institute a 3rd party email service that I’m able to access with my owned domain names. Pain, however the only solution that I was able to find…
