Smtp server and dkim

[mjac1521]

Hi guys super incredible how easy, simplified and clean all the instalation of smtp, jmap and imap servers are. Well done.

I habe a question. I installed jmap and created multiple domains and each of it has it own dkim generated using the jmap cli and stored in rockdb. I have also installed the smtp server wich is autenticating through imap wich get the user info from jmap I also setup lmtp to send incoming emails to jmap.

My question is if an email client let say outlook send an email from any domain to an external email through the smtp server will the smtp server be able to get the dkim key for the specific domain stored in the jmap rockdb and attached to the email?

Hi Maykel,

At the moment Stalwart SMTP and JMAP are not fully integrated and each one uses their own DKIM keys. So, if you send an email from Outlook the message will be signed using the DKIM key configured in the SMTP server. And if you send a message using JMAP submissions, it will be signed using the keys configured in RocksDB.

However this is for the time being, both servers are currently being integrated and the next release will allow DKIM keys to be configured only in a single place.

Thank you for the fast answer. One last question, is it possible for the smtp server to handler dkim for multiple domain? I mean could I store the dkim information like key, cert, selector, domain, etc. in mysql and have the smtp server get it from the database?

I've just released version 0.1.2 which should fix this problem.

Hi,

In order to upgrade I just ran the same command used to install
curl --proto '=https' --tlsv1.2 -sSf https://smtp.stalw.art/install.sh | sudo sh

From the CLI
root:/home/ubuntu# /usr/local/stalwart-smtp/bin/stalwart-cli --version
stalwart-cli 0.2.0

From the smtp log
Starting Stalwart SMTP server v0.1.1..

From your last comment it should upgrade to 0.1.2. I am not sure if it was really upgraded or not.

I haven't had the chance to create an upgrade script yet. But since this is a minor upgrade you can simply download the new binary from https://github.com/stalwartlabs/smtp-server/releases/tag/v0.1.2 and replace it under /usr/local/stalwart-smtp/bin.
