NAME

       aerc-smtp - SMTP configuration for aerc(1)

SYNOPSIS

       aerc implements the SMTP protocol as specified by RFC 5321.

CONFIGURATION

       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
