MuttエラーSMTPセッションに失敗しました：読み取りエラー

set ssl_starttls=yes
set ssl_force_tls=yes

set imap_user = '[email protected]'
set imap_pass = 'password'

set from='[email protected]'
set realname='[email protected]'

set folder = imaps://imap.gmail.com/
set spoolfile = imaps://imap.gmail.com/INBOX
set postponed="imaps://imap.gmail.com/[Gmail]/Drafts"

set header_cache = "~/.mutt/cache/headers"
set message_cachedir = "~/.mutt/cache/bodies"
set certificate_file = "~/.mutt/certificates"

set smtp_url = 'smtp://[email protected]:[email protected]:465/'

set move = no
set imap_keepalive = 900

set smtp_pass="secrets"

このエラーは、電子メールを送信すると発生します。サーバーのファイアウォールも閉じており、セキュリティグループのポート465は開いています。 muttでpostfixをインストールする必要がありますか？

Connection to smtp.gmail.com closed SMTP session failed: read error Could not send the message.

受信トレイのメッセージを読むことはできますが、電子メールを送信することはできません。これは私のメール履歴です。
