aerc-smtp - SMTP configuration for aerc(1)

aerc implements the SMTP protocol as specified by RFC 5321.

SMTP configuration may be done interactively with the :new-account command.

In accounts.conf (see aerc-accounts(5)), the following SMTP-specific options are available:

outgoing = <scheme>[+<auth>]://<username>[:<password>]@<hostname>[:<port>]?[<oauth2_params>]

Remember that all fields must be URL encoded. The @ symbol, when URL encoded, is %40.

The value of <scheme> can be:

smtp

SMTP with STARTTLS

smtp+insecure

SMTP without STARTTLS

smtps

SMTP with TLS/SSL

Additionally, you can specify an authentication mechanism like so:

none

No authentication is required to use this SMTP server. You may omit the username and password in this case.

plain

Authenticate with a username and password using AUTH PLAIN. This is the default behavior.

login

Authenticate with a username and password using AUTH LOGIN. This is an obsolete protocol, but is required for some common webmail providers.

oauthbearer

SMTP with TLS/SSL using OAUTHBEARER Authentication. See documentation in aerc-imap(5) for usage.

xoauth2

SMTP with TLS/SSL using XOAUTH2 Authentication. See documentation in aerc-imap(5) for usage.

outgoing-cred-cmd = <command>

Specifies the command to run to get the password for the SMTP account. This command will be run using sh -c [command]. If a password is specified in the outgoing option, the password will take precedence over this command.

Example:

outgoing-cred-cmd = pass hostname/username

smtp-domain = <domain>

Local domain name to use in the HELO/EHLO SMTP command. Set this to a fully qualified domain name if the server requires it as an antispam measure.

Default: localhost
