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:

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。
