I am trying to send email through org.apache.commons.mail api in Java under Linux Centos.

I was able to send emails, but now suddenly when I am trying to send email I am getting the error – 

com.sun.mail.smtp.SMTPSendFailedException: 452 4.4.5 Insufficient disk space; try again later
at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:2114)
at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:1618)
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1119)
at javax.mail.Transport.send0(Transport.java:195)
at javax.mail.Transport.send(Transport.java:124)

I am not understanding why this is happening. Can anybody please help me to resolve this problem.

Thank you

    I suppose there is no sufficient space in your SMTP server. The error code 452 from RFC821 confirms the same. So check out for storage space in your SMTP server.
