sendEmail實現郵件發送，遭遇invalid SSL_version，同時對於使用騰訊的免費企業郵箱也有一些問題，下面是故障描述及解決方案。
1、故障現象
[root@VM_106_88_centos ~]# sendEmail -f [email protected] -t [email protected] -s smtp.163.com -u \ "i am the subject" -o message-content-type=html -o message-charset=utf8 \ -xu [email protected] -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、環境
[root@VM_106_88_centos ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
二、解決方案
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)
由於在CentOS 7下perl的版本爲5.16，而centos6.5的是5.10，版本不兼容2、解決方案
a、卸載現有的perl版本，安裝老版本(不推薦) b、增加參數-o tls=no 選項 [root@VM_106_88_centos ~]# sendEmail -f [email protected] -t [email protected] -s smtp.163.com -u \ "i am the subject" -o message-content-type=html -o message-charset=utf8 \ -xu [email protected] -xp mypassword -m "i am the contenter" -o tls=no Dec 27 16:16:34 localhost sendEmail[13958]: Email was sent successfully!
