sendmail问题请教

我的是redhat7。0
sendmail一直使用良好。
现在发现一个用户出现问题

from localhost [127.0.0.1]

   ----- The following addresses had permanent fatal errors -----
<jirongxin@mail.xxx.xx.cn>
    (reason: can't create (user) output file)

   ----- Transcript of session follows -----
procmail: Quota exceeded while writing "/var/spool/mail/jirongxin"
550 5.0.0 <jirongxin@mail.xxx.xxx.cn>... Can't create output
后查看/var/spool/mail/jirongxin都很正常。
后修改/var/spool/mail/jirongxin文件,在里面身边加几个字符。
后能正常。但寄信超过3封又出现以上问题。
