## Configuring inbound reply emails

<Note>
|
|
Conversation Continuity requires your chatwoot installation to have a [cloud storage configured](/docs/self-hosted/deployment/storage/supported-providers)

There are a couple of email infrastructure service providers to handle the incoming emails that we support at the moment. They are
|
|
Sendgrid, Mandrill, Mailgun, Exim, Postfix, Qmail and Postmark.
|
|
|
|
Step 1 : We have to set the inbound email service used as an environment variable.
|
|
|
|
```bash
|
|
# Set this to appropriate ingress service for which the options are :
|
|
# "relay" for Exim, Postfix, Qmail
|
|
# "mailgun" for Mailgun
|
|
# "mandrill" for Mandrill
|
|
# "postmark" for Postmark
|
|
# "sendgrid" for Sendgrid
|
|
RAILS_INBOUND_EMAIL_SERVICE=relay
|
|
```
|
|
If you wish to use the same local relaying server (for example postfix) to send outbound mail as you are using to relay inbound messages and you opt not to use an external authentication mechanism like SASL which may be the case if the server is handling it own emails only. The upstream SMTP platform Action Mailer attempts to use a default authentication method if the configuration options `SMTP_AUTHENTICATION`, `SMTP_USERNAME` and `SMTP_PASSWORD` are present in your .env file. To disable this behaviour either comment out or delete these lines from your configuration. This will allow you to send outbound messages from the same server without a premium service. Please note many ISP's do not allow email servers to be run from their networks. It is your responsibility to ensure adequate access control preventing yourself becoming an open relay and ensuring your server is able to get past your recipients spam filters for example SPF, DKIM & DMARC dns records.
|
|
|
|
This configures the ingress service for the app. Now we have to set the password for the ingress service that we use.
|
|
|
|
```bash
|
|
# Use one of the following based on the email ingress service
|
|
|
|
# Set this if you are using Sendgrid, Exim, Postfix, Qmail or Postmark
|
|
RAILS_INBOUND_EMAIL_PASSWORD=
|
|
# Set this if you are Mailgun
|
|
MAILGUN_INGRESS_SIGNING_KEY=
|
|
# Set this if you are Mandrill
|
|
MANDRILL_INGRESS_API_KEY=
|
|
```
|
|
|
|
### Mailgun
|
|
If you are using Mailgun as your email service, in the Mailgun dashboard configure it to forward your inbound emails to `https://example.com/rails/action_mailbox/mailgun/inbound_emails/mime` if `example.com` is where you have hosted the application.
|
|
|
|
#### Getting Mailgun Ingress Key
|
|
|
|
|
|
### Sendgrid
|
|
|
|
Ensure to set up the proper MX records for `your-domain.com` pointed towards Sendgrid
|
|
|
|
Configure SendGrid Inbound Parse to forward inbound emails to forward your inbound emails to `/rails/action_mailbox/sendgrid/inbound_emails` with the username `actionmailbox` and the password you previously generated. If the deployed application was hosted at `example.com`, you can configure the following URL as the forward route.
|
|
|
|
```bash
|
|
https://actionmailbox:PASSWORD@example.com/rails/action_mailbox/sendgrid/inbound_emails
|
|
```
|
|
|
|
When configuring your SendGrid Inbound Parse webhook, be sure to check the box labeled "Post the raw, full MIME message." Action Mailbox needs the raw MIME message to work.
|
|
|
|
### Mandrill
|
|
If you are configuring Mandrill as your email service, configure Mandrill to route your inbound emails to `https://example.com/rails/action_mailbox/mandrill/inbound_emails` if `example.com` is where you have hosted the application.
|
|
|
|

|
|

|
### IMAP via getmail
|
|
Chatwoot receives inbound emails through the [Action Mailbox](https://edgeguides.rubyonrails.org/action_mailbox_basics.html) feature of Ruby on Rails. Action Mailbox supports various 'ingresses' by default. They are defined in [here](https://github.com/rails/rails/blob/main/actionmailbox/lib/tasks/ingress.rake) and can be executed through `bin/rails`. For example
|
|
```bash
|
|
cat my_incoming_message | ./bin/rails action_mailbox:ingress:postfix \
|
|
RAILS_ENV=production \
|
|
URL=http://localhost:3000/rails/action_mailbox/postfix/inbound_emails \
|
|
INGRESS_PASSWORD=...
|
|
```
|
|
would import the contents of the file `my_incoming_message` into a Chatwoot instance running on `localhost` - assuming `my_incoming_message` contains an [RFC 822](https://datatracker.ietf.org/doc/html/rfc822) compliant message.
|
|
|
|
The ingress tasks provided by Action Mailbox are a thin layer around an HTTP endpoint exposed by Action Mailbox. An alternative to using those tasks is to talk to the http endpoint directly. The following script achieves the same.
|
|
```bash
|
|
INGRESS_PASSWORD=...
|
|
URL=http://localhost:3000/rails/action_mailbox/relay/inbound_emails
|
|
|
|
curl -sS -u "actionmailbox:$INGRESS_PASSWORD" \
|
|
-A "Action Mailbox curl relayer" \
|
|
-H "Content-Type: message/rfc822" \
|
|
--data-binary @- \
|
|
$URL
|
|
```
|
|
|
|
The popular mail retrieval system [getmail6](https://github.com/getmail6/getmail6) can be used to fetch mails and import them into Chatwoot. If the curl script above is stored in `/home/chatwoot/bin/import_mail_to_chatwoot`, a configuration for doing so from an IMAP inbox is as follows.
|
|
```
|
|
[retriever]
|
|
type = SimpleIMAPSSLRetriever
|
|
server = ...
|
|
username = ...
|
|
password = ...
|
|
|
|
[destination]
|
|
type = MDA_external
|
|
path = /home/chatwoot/bin/import_mail_to_chatwoot
|
|
|
|
[options]
|
|
verbose = 0
|
|
read_all = false
|
|
delete = false
|
|
delivered_to = false
|
|
received = false
|
|
message_log = /home/chatwoot/logs/import_imap.log
|
|
message_log_syslog = false
|
|
message_log_verbose = true
|
|
```
|
|
|
|
For mail to be imported you'll need to execute `getmail` regularly, for example using a cron job. For `IMAP` you can also run it constantly using `getmail --idle INBOX`, though that will need some care to deal with interrupted connections, etc.
|
|
|
|
## Configure inbound email domain environment variable
|
|
|
|
Add the following environment variable with the value `your-domain.com`, where `your-domain.com` is the domain for which you set up MX records in the previous step.
|
|
|
|
```bash
|
|
MAILER_INBOUND_EMAIL_DOMAIN=
|
|
```
|
|
|
|
After finishing the set up, the mail sent from Chatwoot will have a `replyto:` in the following format `reply+<random-hex>@<your-domain.com>` and reply to those would get appended to your conversation. |
