Cannot get dovecot to work?

bscho · 04-25-2020, 12:41 AM

Using Fedora 31 Cinnamon I am hosting a site with a shopping basket and this appears to be my last problem.

I am making a video of the fastest gaming and hosting PC for my channel on Youtube. I have the hosting working fine but have not been able to see any emails on the system. When I send an email to admin@windows12shop.com
it appears to have gone OK. I cannot find any folder with an email in. Then days later it says it cannot be delivered.

I am now going to delete Dovecot and start again.

Would like a step by step installation of Dovecot as Google has not helped.

Anyone done this before and has it working on LQ?

Step by step: https://www.dovecot.org/

I always recommend going to the source.

I don't find an MX record for windows12shop.com. Sending email programs don't know where to deliver to.

PS: I, for one, won't use a shopping cart on an insecure site.

It is a secure site why do you say that.

I don't find an MX record for windows12shop.com. Sending email programs don't know where to deliver to.

I did make one I will check again with the dns host.

Thanks.

Sorry, no. windows12shop.com Is not secure (http...not https)
But off topic...sorry. I suspect the root cause of your problem is no MX record.

It has a certificate it is https://windows12shop.com

Are you saying you cannot find it with https:// I can?

And Square can as they would not have allowed me to take payments.

Ahh. If one just puts the domain name in the browser, it resolves to http. You need to redirect http requests to https. Don’t depend on the visitor to provide it.

If you put https:// it will not find it if it is not a secure site. Have you tried https://windows12shop.com ?

How do you check for the MX record?

Code:

dig domainname mx
Or
dig domainname any

Please reread #6. The issue is not that there’s no https, but that you’re requiring the visitor to supply it.

Does this mean the MX is OK?

Re #11.
No. The query return no answer. There is no ANSWER SECTION:. There is no MX record.

Code:

dig windows12shop.com any

See? No MX record.

Oh OK will wait for help from the dns providers. Thanks.

bscho · 04-26-2020, 08:16 AM

My DNS and MX provider is not helping very much. I entered this

MX Records (2) 
Add MX Record
Host Name Points To Priority
www www.windows12shop.com 65535 Edit Remove
windows12shop.com 65535 Edit Remove

Which does not appear to work the DNS which does work is

A Records (2) 
Add A Record
Host Name Points To
www 151.227.205.133 Edit Remove
151.227.205.133 Edit Remove

I feel sure the MX record should point to 151.227.205.133 but it will not let me enter an ip only a domian name

Have you any ideas as my ip provider clearly has not done this before and wants me to make an email on their site?

scasey · 04-26-2020, 11:21 AM

Yes. MX records point to domain names. The domain name’s A record points to the IP address.
Your domain name doesn’t have an A record for www. (nor does it need one), so don’t include that in the MX

Code:

windows12shop.com.      3600    IN      MX   windows12shop.com

Should work
