| Advanced | Email Gathering with Getmail |
To enable the getmail service to retrieve e-mails set the environment variable ENABLE_GETMAIL to 1. Your compose.yaml file should include the following:
environment:
- ENABLE_GETMAIL=1
- GETMAIL_POLL=5
In your DMS config volume (eg: docker-data/dms/config/), create a getmail-<ID>.cf file for each remote account that you want to retrieve mail and store into a local DMS account. <ID> should be replaced by you, and is just the rest of the filename (eg: getmail-example.cf). The contents of each file should be configuration like documented below.
The directory structure should similar to this:
├── docker-data/dms/config
│ ├── dovecot.cf
│ ├── getmail-example.cf
│ ├── postfix-accounts.cf
│ └── postfix-virtual.cf
├── docker-compose.yml
└── README.md
Configuration
A detailed description of the configuration options can be found in the online version of the manual page.
Common Options
The default options added to each getmail config are:
[options]
verbose = 0
read_all = false
delete = false
max_messages_per_session = 500
received = false
delivered_to = false
If you want to use a different base config, mount a file to /etc/getmailrc_general. This file will replace the default "Common Options" base config above, that all getmail-<ID>.cf files will extend with their configs when used.
??? example "IMAP Configuration"
This example will:
1. Connect to the remote IMAP server from Gmail.
2. Retrieve mail from the gmail account `alice` with password `notsecure`.
3. Store any mail retrieved from the remote mail-server into DMS for the `user1@example.com` account that DMS manages.
```getmailrc
[retriever]
type = SimpleIMAPRetriever
server = imap.gmail.com
username = alice
password = notsecure
[destination]
type = MDA_external
path = /usr/lib/dovecot/deliver
allow_root_commands = true
arguments =("-d","user1@example.com")
```
??? example "POP3 Configuration"
Just like the IMAP example above, but instead via POP3 protocol if you prefer that over IMAP.
```getmailrc
[retriever]
type = SimplePOP3Retriever
server = pop3.gmail.com
username = alice
password = notsecure
[destination]
type = MDA_external
path = /usr/lib/dovecot/deliver
allow_root_commands = true
arguments =("-d","user1@example.com")
```
Polling Interval
By default the getmail service checks external mail accounts for new mail every 5 minutes. That polling interval is configurable via the GETMAIL_POLL ENV variable, with a value in minutes (default: 5, min: 1, max: 30):
environment:
- GETMAIL_POLL=1
XOAUTH2 Authentication
It is possible to utilize the getmail-gmail-xoauth-tokens helper to provide authentication using xoauth2 for gmail (example 12) or Microsoft Office 365 (example 13)
