在Linux下配置简单的邮件发送，mail 加上uuencode方式或者mutt方式，都不是很理想。因此还是继续使用之前用过的sendEmail来实现邮件发送，这还真不巧，遭遇invalid SSL\_version，同时对于使用腾讯的免费企业邮箱也有一些问题，下面是故障描述及解决方案。

## 一、故障现象及环境 ##

### 1、故障现象 ###

# sendEmail -f cgh@163.com -t leshami@qq.com -u "TestMail" -s smtp.163.com -xu cgh -xp passwd \
    > -m "This is test mail from Robinson" 
    *******************************************************************
     Using the default of SSL_verify_mode of SSL_VERIFY_NONE for client
     is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER
     together with SSL_ca_file|SSL_ca_path for verification.
     If you really don't want to verify the certificate and keep the
     connection open to Man-In-The-Middle attacks please set
     SSL_verify_mode explicitly to SSL_VERIFY_NONE in your application.
    *******************************************************************
      at /usr/local/bin/sendEmail line 1906.
    invalid SSL_version specified at /usr/share/perl5/vendor_perl/IO/Socket/SSL.pm line 415

### 2、环境 ###

# cat /etc/redhat-release 
    CentOS Linux release 7.2.1511 (Core)

## 二、解决方案 ##

### 1、SSL.pm文件415行 ###

415     ${ *$self}{
       '_SSL_ctx'} = IO::Socket::SSL::SSL_Context->new($arg_hash) || return;
    
    # perl -v
    
    This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
    (with 29 registered patches, see perl -V for more detail)
    
    由于在CentOS 7下perl的版本为5.16，而centos6.5的是5.10，版本不兼容

### 2、解决方案 ###

a、卸载现有的perl版本，安装老版本(不推荐)
    b、增加参数-o tls=no 选项
    # sendEmail -f cgh@163.com -t leshami@qq.com -u "TestMail" -s smtp.163.com -xu cgh -xp passwd \
    > -m "This is test mail from Robinson" -o tls=no
    Sep 28 09:49:55 hn249 sendEmail[127791]: Email was sent successfully!

### 3、其他问题(腾讯免费邮箱不支持传统的smtp 25号端口方式 ###

# sendEmail -f chengguohua@htyjie.com -t leshami@qq.com -u "TestMail" -s smtp.exmail.qq.com -xu chengguohua -xp passwd \
    > -m "This is test mail from Robinson" -o tls=no
    Sep 28 10:00:16 hn249 sendEmail[127844]: ERROR => ERROR => SMTP-AUTH: Authentication to smtp.exmail.qq.com:25 failed.
