sendEmail使用TLS发送邮件

SendEmail使用TLS发送邮件

在使用sendEmail启用tls发送邮件的时候出现

sendEmail[32136]: ERROR => No TLS support! SendEmail can't load required libraries. (try installing Net::SSLeay and IO::Socket::SSL)

我的CentOS 6.7，则安装

yum -y install perl-IO-Socket-SSL openssl-perl openssl-devel

即可

sendEmail报错：at /usr/share/perl5/vendor_perl/IO/Socket/SSL.pm

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.

sendEmail发邮件的时候，出现的报错，然后查阅了很多资料

在http://caspian.dotconf.net/menu/Software/SendEmail/

上找到了 下面这段话

Q: I get the error "invalid SSL_version specified at /System/Library/Perl/Extras/5.16/IO/Socket/SSL.pm line 332.a on my Apple. What do I do?
A: Here's what I got from one user. It's a workaround until I put a real fix in:
> Fixed it by using Perl v5.12 that's still on OSX Mavericks. > (just changed sendEmail line 1 from #!/usr/bin/perl -w to #!/usr/bin/perl5.12 -w)

centos7.2默认是 perl的版本是5.16，centos6.5的是5.10，后来把7的版本换成5.10，就可以正常发邮件了。

perl安装

     wget http://www.cpan.org/src/5.0/perl-5.10.0.tar.gz
     tar -zxf perl-5.10.0.tar.gz
     cd perl-5.22.0
     ./configure.gnu -des -Dprefix=/usr/local/perl
     echo $?
     make
     make test
     make install
     mv /usr/bin/perl /usr/bin/perl.bak
     ln -s /usr/local/perl/bin/perl /usr/bin/perl
     perl -v

解决方法：

有两种方法修复问题：

1，不使用 TLS 加密

添加选项：-o tls=no

2，修改 sendEmail 脚本：

第 1906 行，将 'SSLv3 TLSv1' 修改为 'SSLv23:!SSLv2'：
