Issues with DKIM and Email Alias

Decepticon · January 21, 2024, 9:51am

Hello community, I’m encountering difficulties with configuring DKIM and Email Alias, and I would greatly appreciate any help:
1/ How to set the default DKIM key to be 2048 bits instead of 1024 bits
I’ve found two methods to achieve this, but both are somewhat inconvenient:

Using the CLI command: v-add-mail-domain user mydomain.tld no no yes 2048
Using the web interface: Add the mail domain without DKIM, then edit the domain and enable DKIM ([Bug] DKIM key is 1024 bits when adding a mail domain · Issue #4026 · hestiacp/hestiacp · GitHub)

2/ How to create multiple Email Aliases via the command line?
I’ve tried several different command variations but none worked

v-add-mail-account-alias user mydomain.com test alias1 alias2
v-add-mail-account-alias user mydomain.com test alias1,alias2
v-add-mail-account-alias user mydomain.com test alias1;alias2

If someone could provide clear instructions on how to address these issues, I would be extremely grateful.

Thank you, everyone!

Default is already 2048 bits but it needs to be enabled seperatly …

v-add-mail-domain user mydomain.tld no no yes should be enough…

For aliasses

v-add-mail-account-alias user mydomain.com test alias1
v-add-mail-account-alias user mydomain.com test alias2

And so on…

Are you sure? I’ve installed HestiaCP on 5 VPS, and by default, DKIM is always 1024 bits, whether I add mail domains through the CLI or the web interface.

P/s: My second question was quite silly :)))

          # load config file
          source_conf "$HESTIA/conf/hestia.conf"

When empty it should be 2048

It got changed on the mail branch but has not reached release branch yet …

Here is a screenshot from /usr/local/hestia/bin/v-add-mail-domain on my VPS. To make DKIM default to 2048, I just need to change 1024 to 2048, right?

eris · January 21, 2024, 11:33am

Yes …

Decepticon · January 21, 2024, 11:43am

Thank you. It worked perfectly.
It’s strange that v-add-mail-domain is outdated even though HestiaCP has been updated to 1.8.11.

Main branch != release branch …

Main branch is used for development…
