I am using JavaMail to send email. But I got this error message as bellows:
This is not program's problem. This error may resulted from SMTP server.
It may :
- The ISP server’s disk system has run out of storage space, so the action had to be cancelled.
- Most ISPs mail servers impose a maximum number of concurrent connections that client’s mail servers can attempt to make, and they usually also have a limit on the number of messages that are sent per connection.
- This error can also be indicative of a problem on your own mail server. ex. out of memory.
