Postmark outbound integration
-
@crazybrad currently, we don't do any automation with respect to outbound email relays, it only uses SMTP. I agree though it would be nice to have some automation going and maybe even use API to send emails instead of SMTP (that way we get deliverability reports etc as well).
-
@girish I'm not sure I explained my use case properly. We are using the Smart Host feature and providing the Postmark API key. Cloudron is using SMTP to send the mail, but Postmark fails to send the mail without a proper Sender Signature. In checking further, automation would require entering the account API key (not just the SMTP token), not something that is currently requested in the outbound email relay form. Perhaps a warning message (similar to SPF record) is enough for now. Automation is much more involved. And if you did this for Postmark, you might need to do so for every other provider too(: Since I am new to Cloudron, is entering the DNS records needed (which I did at Porkbun) the proper procedure?
Should I sync DNS after a manual change in DNS records (remember seeing this somewhere else)?
-
Think I understand now - for each provider we have to outline the bunch of steps needed to get it ready to send email.

Cloudron manages the records that are related to apps (and the mail server, if you use it). Other than that, you can add/delete/update records in the DNS directly. You don't usually ever have to manually sync DNS records . What kind of records were you adding into Porkbun?
-
@crazybrad By sync, I assume you mean https://docs.cloudron.io/domains/#sync-dns ? If so, that is not needed. The sync button is only syncing records that Cloudron knows about.
"Email related" records was an overly broad term I used. The records that Cloudron sets up specifically are:
- MX record - if incoming email is enabled
- SPF record - the TXT record is upserted with the mail server domain name
- DMARC - a TXT record with the default DMARC policy
- DKIM - a TEXT record with the DKIM key to sign cloudron emails. DNS can have many DKIM keys and this one is specific to Cloudron mail server. It's not related to the Postmark DKIM record.
Apart from the above, it has no clue about other records (including the postmark records)!

@girish Thank you for this thorough explanation. Now that I understand the purpose of sync-dns and which DNS records are created by Cloudron, I am thinking that the SPF record created by Cloudron (which I manually edited to include the Postmark mail server) should be "synced". Is this correct?
-
@crazybrad to clarify further, "sync" here just means Cloudron is adding/updating entries in your domain provider. So, if you delete the A record of an app directly in your domain provider, if you click the "sync" button, Cloudron will re-add that A record back. With that in mind, if you deleted or tampered or changed the SPF record in your domain provider, clicking "sync" will bring it back.
