I am a beginner of webdevelopment and have successfully deployed my website at Netlify. I bought a domain with email hosting at one.com and now I want to redirect it to Netlify DNS to be provided with their TLS certificate, as the plan I bought from one.com doesn't have this. But the problem is that Netlify doesn't provide email but I am able to save it by copying the MX records at one, which I can't find anywhere. I successfully set up the domain email on gmail through IMAP, but don't know if it's encrypted. Is there any way to solve this, or should I just give up on the email hosting?

Google does require encryption for IMAP and SMTP through their servers From their help document (emphasis added):

Incoming Mail (IMAP) Server

  • imap.gmail.com
  • Requires SSL: Yes
  • Port: 993

Outgoing Mail (SMTP) Server

  • smtp.gmail.com
  • Requires SSL: Yes
  • Requires TLS: Yes (if available)
  • Requires Authentication: Yes
  • Port for SSL: 465
  • Port for TLS/STARTTLS: 587

So if you have mail set up with Google, I'd think you are good and you should stop there. However if you want to find your MX records used at one.com you should be able to look them up from their nameservers. I don't know what their nameservers actually are, but they are problably something like ns1.one.com and ns2.one.com. The actual values should be in your account. You can use dig on the command line to find the MX records:

dig @ns1.one.com MX mydomain.example
  • Thank you! It seems that POP3 is the method to set up domain email through gmail on Macbook? Is that as safe as IMAP?

  • Google also uses TLS for POP3. Mac mail clients support IMAP and I recommend using it if possible. It is designed to work with multiple folders and leave mail on the server. POP is a holdover from when email was assumed to be one mailbox folder that got downloaded locally and deleted from the server. Dec 7, 2021 at 14:23
  • Ok, thanks for the answer. So, if I want to recieve domain emails through Gmail but still point the DNS servers to Netlify to host the website, I would need to change the MX records to Gmail server at one.com?

  • Your MX records control which server receives the email for your domain. It is a bit unclear to me who is hosting your DNS now. If your NS records point to netlify, you need to set the MX records there. If your NS records point to one.com you need to set the MX records there. Dec 8, 2021 at 11:08
