Install the plugin as usual.
The plugin requires free Postmark account to process incomming emails.
1. Go to PostMark site and create a free account, if you don’t already have it.
2. You should get free credit to process 25k messages. After it there are affordable tariffs that allow you to pay as you go ($1.5 per 1000 emails).
3. Log on to the site.
4. Create server.
5. Create sender’s signature (you can skip this step if you do not plan to send mails via PostMark – notifications are sent with standard wordpress function )
6. Go to Credentials tab and copy Server API Token. Enter API Token into plugin setting’s dialog.
7. Copy the hook from the plugin setup dialog.
8. On PostMark server, go to Settings tab and choose Inbound. Paste the Inbound Webhook and click Check. You should get response like below.
9. Note down the Inbound email address.
10. If you want a reply-to address in your domain you need to have a proper forward set up on your e-mail server. Alternatively, you can set PostMark inbound address directly in the plugin as a reply to address – it is simpler, but users will see inbound.postmark.com as a domain.
In your domain create address for receiving replies (ie. email@example.com) and forward all messages from there to the address from previous point. Please note that your tool to manage the e-mail service is most likely different from mine, as every ISP uses it’s own (CPanel or similar).
That’s how this looks on mine e-mail service:
The redirect should look like this:
10. Send a test email to this address, it should apprear in PostMark inbox. It will get stuck there, as the plugin will reject it as it does not have the right hash.
