In complex environments there are from time to time processes that cannot be automated, either because you lack the authority to make it so, or because not everyone agrees to a common approach. - If you cannot automate a specific step, but the step is non-blocking, sending out an email to the responsible party to make them perform their part of the bargain is an elegant way to put the responsibility in someone else's lap. - Of course sending out a mail can be equally useful as a way to notify one or more people in a team that a specific action has been (successfully) taken. options: sender: description: - The email-address the mail is sent from. May contain address and phrase. type: str default: root aliases: [ from ] to: description: - The email-address(es) the mail is being sent to. - This is a list, which may contain address and phrase portions. type: list elements: str default: root aliases: [ recipients ] cc: description: - The email-address(es) the mail is being copied to. - This is a list, which may contain address and phrase portions. type: list elements: str default: [] bcc: description: - The email-address(es) the mail is being 'blind' copied to. - This is a list, which may contain address and phrase portions. type: list elements: str default: [] subject: description: - The subject of the email being sent. required: true type: str aliases: [ msg ] body: description: - The body of the email being sent. type: str username: description: - If SMTP requires username. type: str password: description: - If SMTP requires password. type: str host: description: - The mail server. type: str default: localhost port: description: - The mail server port. - This must be a valid integer between 1 and 65534 type: int default: 25 attach: description: - A list of pathnames of files to attach to the message. - Attached files will have their content-type set to C(application/octet-stream). type: list elements: path default: [] headers: description: - A list of headers which should be added to the message. - Each individual header is specified as C(header=value) (see example below). type: list elements: str default: [] charset: description: - The character set of email being sent. type: str default: utf-8 subtype: description: - The minor mime type, can be either C(plain) or C(html). - The major type is always C(text). type: str choices: [ html, plain ] default: plain secure: description: - If C(always), the connection will only send email if the connection is Encrypted. If the server doesn't accept the encrypted connection it will fail. - If C(try), the connection will attempt to setup a secure SSL/TLS session, before trying to send. - If C(never), the connection will not attempt to setup a secure SSL/TLS session, before sending - If C(starttls), the connection will try to upgrade to a secure SSL/TLS connection, before sending. If it is unable to do so it will fail. type: str choices: [ always, never, starttls, try ] default: try timeout: description: - Sets the timeout in seconds for connection attempts. type: int default: 20 ehlohost: description: - Allows for manual specification of host for EHLO. type: str version_added: 3.8.0 ''' EXAMPLES = r''' - name: Example playbook sending mail to root community.general.mail: subject: System {{ ansible_hostname }} has been successfully provisioned. delegate_to: localhost - name: Sending an e-mail using Gmail SMTP servers community.general.mail: host: smtp.gmail.com port: 587 username: username@gmail.com password: mysecret to: John Smith subject: Ansible-report body: System {{ ansible_hostname }} has been successfully provisioned. delegate_to: localhost - name: Send e-mail to a bunch of users, attaching files community.general.mail: host: 127.0.0.1 port: 2025 subject: Ansible-report body: Hello, this is an e-mail.
