MORE INFORMATION

Before you apply the hotfix that is described in this article, the POP3 adapter will retry processing the malformed message until the POP3 adapter reaches the error threshold. After the error threshold is reached, the POP3 adapter is disabled. Therefore, valid messages in the mailbox are not processed as expected.

After you install this hotfix, the malformed message is suspended, and the POP3 adapter processes subsequent messages as expected.
