Cant not detect AAAA record and how to renew cer if website and email different server?


#1

Dear,

I have two problems with my email server:

1.
I have update AAAA record in CloudFlare, but system can’t not detect. AAAA 2404:f080:1101:0316:a163:0044:0207:050f and 2404:f080:1101:316:a163:44:207:50f is different?

Error:
This domain should resolve to your box's IP address (AAAA 2404:f080:1101:0316:a163:0044:0207:050f) if you would like the box to serve webmail or a website on this domain. The domain currently resolves to 2404:f080:1101:316:a163:44:207:50f in public DNS. It may take several hours for public DNS to update after a change. This problem may result from other issues listed here.

2.
My website and mail server is different server, so how can I renew certificate

  1. abc.com > 123.123.123.123
  2. mail.abc.com > 111.111.111.111

Thank for your help!

This one may help you to guess how to.

Note: Just ignore the OLD Wosign part mentioned there, as It is currently not available/ recommended.

  1. That’s normal and isn’t a problem (mine’s the same way). AAAA addresses often drop leading zeroes, but they’re equivalent. It’s not a Cloudflare issue, as I’m using my MIAB server for DNS and it also demonstrates the leading zero discrepancy.

  2. Maybe I’m missing something, but aren’t you only getting a certificate for a specific subdomain? MIAB is going to request a certificate for mail.abc.com. Let’s Encrypt is only going to look at mail.abc.com when it issues the certificate.

I tried added email demo@mail.my-domain.com. It’s working, Mail-in-a-Box auto adds more domain (mail.my-domain.com) and I just install Let’s Encrypt.

Thank for your ideal :smiley:

Hi @Locker,
1.
Yesterday Mail-in-a-Box don’t approve of installing Let’s Encrypt b/c AAAA is different. Today is Ok, I don’t know why … Lucky for me :sunny:

The error is still there: This domain should resolve to your box's IP address (AAAA 2404:f080:1101:0316:a163:0044:0207:050f) if you would like the box to serve webmail or a website on this domain. The domain currently resolves to 2404:f080:1101:316:a163:44:207:50f in public DNS. It may take several hours for public DNS to update after a change. This problem may result from other issues listed here.

I have solutions for it, add more email like demo@mail.my-domain.com and Mail-in-a-Box auto created a new domain in the system and I just installed Let’s Encrypt :smiley:

Thank for your help!
