sendEmail实现邮件发送,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。
1、故障现象
[root@VM_106_88_centos ~]# sendEmail -f from@163.com -t to@qq.com -s smtp.163.com -u \ "i am the subject" -o message-content-type=html -o message-charset=utf8 \ -xu from@163.com -xp mypassword -m "i am the contenter" ******************************************************************* 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
[root@VM_106_88_centos ~]# 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 [root@VM_106_88_centos ~]# sendEmail -f from@163.com -t to@qq.com -s smtp.163.com -u \ "i am the subject" -o message-content-type=html -o message-charset=utf8 \ -xu from@163.com -xp mypassword -m "i am the contenter" -o tls=no Dec 27 16:16:34 localhost sendEmail[13958]: Email was sent successfully!
