Error A969 and A8 when appending messages

[bravedreamer]

Hi there

I'm programming a small sync client which synchronizes Exchange and Zimbra. Unfortunately, I'm facing now a strange problem. As side notes: I'm using JavaMail 1.4.0 to connect to Zimbra via IMAP. I use the most actual Zimbra version.

I get the following errors:

javax.mail.MessagingException: A969 NO [TOOBIG] request too long;
  nested exception is:
	com.sun.mail.iap.CommandFailedException: A969 NO [TOOBIG] request too long
	at com.sun.mail.imap.IMAPFolder.doCommand(IMAPFolder.java:2588)
	at com.sun.mail.imap.IMAPFolder.appendMessages(IMAPFolder.java:1417)

and an another position in the program

javax.mail.MessagingException: A8 NO [TOOBIG] request too long;
  nested exception is:
	com.sun.mail.iap.CommandFailedException: A8 NO [TOOBIG] request too long
	at com.sun.mail.imap.IMAPFolder.doCommand(IMAPFolder.java:2588)
	at com.sun.mail.imap.IMAPFolder.appendMessages(IMAPFolder.java:1417)

As I just mentioned it is the 'appendMessages' command which is executed on a folder which makes the problems. Unfortunately, I don't know what this error message should mean. Is there somewhere a description of the error messages Zimbra returns (in my case for IMAP connections)? What is the difference between both? A8? A969?

Another side remark: I try to append 100 Mails at a time.

Any suggestions?

It sounds like a quota limit error... check email sizes y your quota limit.

This is not a Zimbra Desktop issue. Please move it to the appropriate section.
