用pop3或者imap收邮件的各种错误，实在搞不出来，望高手指点！！！！！
126，163，sina，139都是行的。
hotmail ：imap_open({pop.live.com:110/pop3}inbox,xxx,xxx);
imap_errors() 输出：[0] => connection failed to rds.live.com.nsatc.net,110: connection timed out
{imap.live.con:993/imap/ssl}inbox
imap_errors() 输出：[0] => can't connect to nj.redirect.local,993: connection timed out
qq ：{pop.qq.com:110/pop3}inbox
imap_errors() 输出：[0] => 454 popδ: http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=166 account is not enabled for pop access. for more details please visit: http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=166
  [1] => pop3 connection broken in response
{imap.qq.com:993/imap/ssl}inbox
imap_errors() 输出：[0] => can not authenticate to imap server:
sohu： {pop.sohu.com:110/pop3}inbox
imap_errors() 输出：[0] => tls/ssl failure for pop.sohu.com: ssl negotiation failed
{imap.sohu.com:993/imap/ssl}inbox
imap_errors() 输出：[0] => tls/ssl failure for imap.sohu.com: ssl negotiation failed
gmail ：{pop.gmail.com:110/pop3}inbox
imap_errors() 输出：[0] => connection failed to gmail-pop.l.google.com,110: connection timed out
  [1] => connection failed to gmail-pop.l.google.com,110: connection timed out
{imap.gmail.com:993/imap/ssl}inbox是可以收到的。
------解决方案--------------------
主要问题在于，了解每个邮件系统支持的功能，比如是否支持pop,是否支持ssl/tls,根据实际情况分别处理。推荐使用phpmailer，封装的不错

估计是人家邮件服务器的问题。不想让你这么玩
