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.
