bugzilla 不能发邮件

由于是租用的邮箱，现在bugzilla 不能发送邮件，主要是下面的提示：
Working on Bugzilla::Job::Mailer ...

job failed: There was an error sending mail from 'bugzilla@richhouseglobal.com' to
'calvin.xie@richhouseglobal.com': Couldn't authenticate
'bugzilla@richhouseglobal.com:...'

使用base64编码： YnVnemlsbGFAcmljaGhvdXNlZ2xvYmFsLmNvbQBidWd6a2WxsYUByaWNoaG91c2wnbG9iYWwuY29tAHJpY2hob3VzZS44OTA=
出现下面的情况：bugzilla@richhouseglobal.com<00>bugzilla@richhouseglobal.com<00>richhouse
邮箱出现两次。但是设置其他邮箱都能发送邮件，请问怎么解决？
