Cloudron Forum

Thank you all! the issue was the unbound service not working and also my email delivery issue too.

Unbound is not resolving, maybe try forwarding all DNS requests. You can do this by running 'cloudron-support --unbound-use-external-dns' option
Using domain server:
Name: 127.0.0.150
Address: 127.0.0.150#53
Aliases:

i get this when i run the command and the i run the suggested command this pops up for me

/usr/bin/cloudron-support: line 803: unbound_use_external_dns: command not found

for further context, heres what the unbound logs say

Hello, so i run my cloudron server in my house, now i have done this before and had no issue with using an external smpt service for email delivery, i used mailgun and have never had an issue.

i used cloudflare for the domain (my dashboard is the only one that is proxyed)
mailgun for the smpt server

So, tested day i setup my SMPT outbound part and nothing seemed to be working. after sending 3 test emails mailgun says they sent. i check my inbox and they in fact send. so, a few hours later i send another test email and nothing........ i went into cloudflare removed all my TXT files ect and re did it , still nothing. i noticed after looking that unbound was yellow and not working might be the problem???

i also have the logs of my email that do have the 3 that confirmed and the rest that were rejected
