mutt SMTP TLS错误发送邮件

当我尝试发送邮件时，出现以下错误：

gnutls_handshake：收到意外的TLS数据包。

这是我的.muttrc（myname，myaddress和mymail是占位符）：

# Automatically log in to this mailbox at startup
set imap_user="myname"
set imap_pass=""
set spoolfile="imaps://imap.myaddress/Inbox"
set folder="imaps://imap.myaddress/Inbox"
set record="=Sent"
set postponed="=Drafts"

# define how to send mails
set smtp_url="smtps://$imap_user:$imap_pass@smtp.myaddress:587"

# activate TLS if available on the server
set ssl_starttls=yes

# always use SSL when connecting to a server
set ssl_force_tls=yes

# wait to enter mailbox manually
set imap_passive

# Automatically poll subscribed mailboxes for new mail (new in 1.5.11)
set imap_check_subscribed

# Reduce polling frequency to a sane level
set mail_check=60

# And poll the current mailbox more often (not needed with IDLE in post 1.5.11)
#set timeout=10

# keep a cache of headers for faster loading (1.5.9+?)
#set header_cache=~/.hcache

# Display download progress every 5K
set net_inc=5

# Cancel a message when subject is blank
set abort_nosubject=yes

# Set default editor
set editor="gvim -v"

# Asks to include message when replying
set include=ask-yes

# Asks to postpone a message when not sent
set postpone=ask-yes

# Ask before printing
set print=ask-yes

# set from to ensure mutt doesn't put user@localhost.localhost 
set from="myemail"
set use_from=yes
set envelope_from="yes"

在端口587上使用smtp提交时，的值smtp_url应以开头"smtp://"，即不以开头"smtps://"。确保已将ssl_starttls设置为也是很重要的"yes"，就像在上面的配置中正确完成的一样。

在设置我自己的服务器时，我遇到了完全相同的问题。可以同时访问客户端和服务器端的日志，很明显这肯定是客户端问题。

以开头的配置选项smtps告诉mutt打开与服务器的ssl加密连接。但是，服务器期望明文的smtp会话，一旦客户端和服务器进行了一些协商，该会话就会变得加密。
