Hi all,
I have just setup my first panel, very slick! However I have a problem with inbound email working. I have checked with MXToolbox and it gives a pass. I am guessing there are issues with the DNS but I am not sure what. I am using Cloudflare, all proxies are off.
Any guidance would be very much appreciated.
Sparky.

Probaly your provider is blocking port 25 on outgoing connection to prevent spam. Try to manualy connect to a smtp server using telnet.

Hi ScIT,
No connection:
Trying 64.233.184.26…
Trying 2a00:1450:400c:c00::1a…
telnet: Unable to connect to remote host: Network is unreachable
Will contact the VPS provider(Oracle). My understanding is port 25 is outbound rather than inbound. Am I mistaken?

Any updates on this yet? I have the same setup as sparky (see below) and inbound mailing is not working while outbound works fine
Oracle free tier VPS (ARM based processor)
Set 25 in for a SMTP traffic destination port
Cloudflare with proxies off for A records (mail and webmail)
MX record in on Cloudflare with priority 10 (copied across from HestiaCP)
Thanks in advance!

Oracle does not allow outbound email on port 25, you need to use an smtp relay service like amazon ses or similar.

https://www.smtp2go.com/ is another option for smtp relay. Or u can find a hosting provider that is willing to unblock port 25.
In the future if you should check if port 25 is open by using telnet. Like this example : telnet ASPMX.L.GOOGLE.COM 25
Make sure you install telnet also.

Sorry, I forgot to mention that I’ve already been using Sendinblue ’s SMTP relay as instructed in this video
With the SMTP relay, outbound email works fine as mentioned above. The issue is the inbound email.
Regarding the telnet command, which host am I supposed to pass in as a parameter? The Oracle server or website domain or Sendinblue’s SMTP hostname?
telnet scratchgolfballs.com.au 25
Trying 104.21.5.143...
Trying 172.67.154.167...
Trying 2606:4700:3033::ac43:9aa7...
Trying 2606:4700:3033::6815:58f...
telnet: Unable to connect to remote host: Network is unreachable
Thanks

Hi terryeah,
I went back and did the install exactly as this video instructs: Best Free VPS Setup 2022 (Hestia on Oracle Cloud Free Tier) Complete Website + Email Tutorial - YouTube
Possibly the same video you have already watched. Follow exactly. Everything is working well for me, hopefully, you will get the same outcome. Update us with your progress.
