我必须发送一封带有shell脚本附件的邮件。 我正在尝试使用 mutt 进行此操作，如下所示：How do I send a file as an email attachment using Linux command line?
命令：
echo "This is the message body" | mutt -a "/path/to/file.to.attach" -s "subject of message" -- recipient@domain.com
错误：

无法发送 消息。

我今天遇到了同样的错误。 我发现我只安装了mutt，但是一旦我安装了sendmail，这个错误就消失了。但是我当地被阻止了。 所以我卸载了sendmail，并安装了postfix这个工作.. 现在收到附有pdf的电子邮件。
这是在企业环境中的RHEL 7.4上。不确定其他版本或环境的结果是否会有所不同。

我遇到此错误，只需将 添加到.muttrc即可。如果重要，我正在使用Gmail。这样我就可以使用别人的服务器来发送，而不必安装额外的垃圾。
set smtp_pass="secrets"
set smtp_url = "smtps://username@gmail.com@smtp.gmail.com:465/"

将this link生成的密码设置到该文件中：
# file: ~/.muttrc
set from="first_name.last_name@gmail.com"
set realname="first_name last_name"
set imap_user="first_name.last_name@gmail.com"
#
# v1.0.1
# check the following google help page:
# http://support.google.com/accounts/bin/answer.py?answer=185833
# that is set here your google application password
set imap_pass="SecretPass!"
#nopeset imap_authenticators="gssapi"
set imap_authenticators="gssapi:cram-md5:login"
set certificate_file="~/.mutt/certificates"
#
# These two lines appear to be needed on some Linux distros, like Arch Linux

###LOCAL FOLDERS FOR CACHED HEADERS AND CERTIFICATES
set header_cache="~/.mutt/cache/headers"
set message_cachedir="~/.mutt/cache/bodies"

我在 Ubuntu 18.04 上遇到了同样的问题，就像@jono一样，我只安装了mutt。安装
sudo apt-get install sendmail
之后，使用测试方法发送邮件或直接通过mutt CLI发送邮件即可。
