Disappearing Mail Record from DNS Configuration After Hestia Update

slavovstudio · February 6, 2025, 7:12am

Hello,
I have the following issue: after every update of Hestia, the A record for mail disappears from the DNS configuration. On some domains, it has been duplicated 10 times.
I checked the template files, and everything seems fine there.
Has anyone experienced a similar issue, and how could it be resolved?

Hi sorry to revive an old thread, but I am having the exact same issue and I see a solution was never proposed.

After every Hestia update the “A” record for mail.domain.xyz gets deleted for every one of my DNS domains. I think it might be occurring as part of the “rebuild mail domain” operation?

Possibly relevant:

In my Hestia configuration, under “Mail Server”, I have “Webmail Alias” set to “mail” rather than the default “webmail”.
When I am looking at the Mail Domains screen and click the “DNS Records” icon next to any of the domains, it shows the mail.domain.xyz A records twice.

Probably less relevant:

I am running on Ubuntu 22.04, with Hestia installed using the official installer on top of a default OS install.
I am running a bind9 cluster with 2 other hosts; the mail host is the DNS master

I appreciate any ideas on where to look (DNS templates maybe?). I host 8 mail domains that users rely on and have downtime after every update until I manually re-add the A records.

Thank you!

I am having the exact same issue that justadri is describing, with the same observations.
Serve this message as a bump, maybe we can get some attention on the issue.

May be related to Hestia updates change custom DNS records

I’ve taken a look at the code and I think that I’ve identified the problem.
A pull request has been submitted to the repository for the maintainers to look at.

[Fix] Disappearing Mail Record from DNS Configuration After Hestia Updates

### **Problem** - In a numerous range of installations we can observe that th…e webmail alias for accessing the mail interface is set to "mail" - As part of the update process for hestia, a rebuild of the dns domains is toggled. This triggers the _v-delete-web-domain-webmail_ and the _v-add-web-domain-webmail_ scripts to be executed one after the other. - The current code in _v-delete-web-domain-webmail_ fails to correctly detect the "mail" alias for the webmail panel, and ends up deleting the DNS A record pointing to mail.domain.com. Afterwards, the _v-add-web-domain-webmail_ also fails to detect (all) aliases and ends up NOT adding back the A record. Summed up, these two scripts are supposed to simply add (and remove) an alias for accessing the webmail, but end up deleting the main entry point for outgoing and incoming mail for the domain (mail.example.com) after each hestia update in installations with "mail" set as an alias for the webmail. This issue is mentioned in forum topics [17837](https://forum.hestiacp.com/t/disappearing-mail-record-from-dns-configuration-after-hestia-update/17837) and [18547](https://forum.hestiacp.com/t/hestia-updates-change-custom-dns-records/18547) ### ***Solution*** - First, I've fixed up the matching logic to correctly detect the correct webmail alias record (and not all the records containing "mail", for example) - Then I've wrapped things up with some extra logic to handle both cases, either when the webmail alias is "mail" and when it is not. This is the most sense I've made out of the code, given the intended scope for the files and checking out [past](https://github.com/hestiacp/hestiacp/commit/e81a4756d27700507d37db13b7259717e56da382) commits for the file. Anyways, just a disclaimer, this is my first pull request to the hestia repository, so if I'm missing the point on some statements or I got some assumptions wrong feel free to correct me out. Regardless, a fix for this problem should be implemented because of how inconvenient it is every time hestia updates.

This issue merits further investigation. Can check what domain template you have selected in the dns domain, and provide the template ?

You can find it here: /usr/local/hestia/install/common/templates/dns

I have replied to the comments in the github pull request and provided more explanations.

Regarding the DNS template, the issue is materializing for me using “default.tpl”
