AERC-SMTP(5) File Formats Manual AERC-SMTP(5) NAME aerc-smtp - SMTP configuration for aerc(1) SYNOPSIS aerc implements the SMTP protocol as specified by RFC 5321. CONFIGURATION Basic 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.
