我正在尝试设置一个cron-job从cpanel服务器发送邮件附件。我发现Mutt是一个很好的选择。但是，我遇到了困难，因为这个错误不断发生。
每当我尝试发送邮件时，我都会收到以下消息：
SASL验证失败。
无法发送邮件。
下面是我的.muttrc文件。

set from = USERNAME@gmail.com
set realname = "NAME"

# set smtp_url = smtp://USERNAME@gmail.com:587/

set smtp_url = "smtps://USERNAME@smtp.gmail.com:465/"
set smtp_pass = PASS
set imap_user = USERNAME@gmail.com
set imap_pass = PASS

set folder = imaps://imap.gmail.com:993
set spoolfile = imaps://imap.gmail.com/INBOX

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

# Etc

set mail_check = 100
set move = no
set imap_keepalive = 900
set sort = threads
set editor = "vim"

# source ~/.mutt/gpg.rc

set ssl_starttls=no
set ssl_force_tls=yes
set smtp_authenticators = "login"

set ssl_verify_host = no
set ssl_verify_dates = no

这可能需要很长的时间（可能解决不了），可能有这个问题的人不多，但我觉得这个帖子可能会在未来帮助其他人
我已经安装了gnutils-bin和openssl

which gnutls-bin
/usr/bin/which: no gnutls-bin in (/usr/local/cpanel/3rdparty/lib/path-bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/opt/cpanel/composer/bin:/usr/local/python3.6/bin:/usr/local/bin:/home/covid/.local/bin:/home/USERNAME/bin)

which openssl
/usr/bin/openssl
