@bathory: the following is the part of the content of sudo nano /etc/cloud/cloud.cfg

Quote:

Looks like I could set the default user as me, pedro, but I can't see how to set the domain name as mywebpage.com

Any tips please?

D'oh the /etc/cloud/cloud.cfg is different from the one mentioned here.
Anyway, you can use the other option mentioned in the hosts file, i.e. edit /etc/cloud/templates/hosts.debian.tmpl and add there the entries you want:

Code:

195.20.254.33 www.mywebpage mywebpage.com
127.0.0.1 www.mywebpage mywebpage.com localhost localhost.localdomain

The TXT is a DNS record that exists for a domain. For example you can use domain that I use for testing all the time (I hope these guys dont hate me for posting this here) is ackits.com

If you do:

# nslookup -q=TXT ackits.com

you will received:

Non-authoritative answer:
ackits.com text = "google-site-verification=oBOD4LuXiwm0yG6_6juHNtNnIGUhzC1
XUO4a6D1qGvE"
ackits.com text = "v=spf1 +ip4:173.231.204.196 +ip4:173.231.229.11 +ip4:209
.182.203.65 +mx +a +include:_spf.google.com ~all"

What this means is that only 173.231.204.196, 173.231.229.11 and 209.182.203.65 are allowed to be sending email on behalf of the domain ackits.com. Most providers like gmail.com or other giants check for the TXT spf records before they accept email.

Do I need to change the default user in /etc/cloud/cloud.cfg??

@HytronBG

What should I put in TXT??

At the moment there are 2 TXT entries, you can see them in the picture I attached. The lower one is:

Quote:

TXT @ "v=spf1 include: spf-eu.ionos.com + ip4: ~all" MAIL

I think I should put this in the VALUE column if my ip4 address is 123.456.789.123

Quote:

"v=spf1 include:_spf-eu.ionos.com + ip4:123.456.789.123 ~all"

No you don't. There is already a default user (ubuntu) and it's not relevant to the mail system

If you have setup the hostname, masquerading, relaying etc, you can try to send an email from CLI to your gmail.com or qq.com account and watch the logs to see what happens:

Code:

mail -s Test you@gmail.com < /dev/null

Thanks again for the tips and advice.

At the moment, I can't seem to get it working. I will read all the tutorials again and try again! At the moment I am trying to get ssl working!

For now, I have changed the contact page: php saves the details from the contact page as a text file in a folder called messages on the cloud server.

I can fetch the messages with a bash script using rsync and save them on this computer. That works fine!
