Get Exception when listing messages

hi all

I use the latest version(v3.6.1.0) of Aspose.Network.

When I tried to write a program to retrieve emails using IMAP protocol from exchange server 2003(sp2), I got an exception.

my code is like:

client.SelectFolder(“INBOX”)
Dim messageInfos As Aspose.Network.Imap.ImapMessageInfoCollection
messageInfos = client.ListMessages()

Then exception occured in “messageInfos = client.ListMessages()”, the message is "Invalid E-Mail Address Format"

Thanks for your help!

Raymond

Hi,

Thank you very much for considering Aspose.Network.

I recommend you to please catch the exception and print the complete text of exception (by using exception.ToString()) and call stack (by using exception.StackTrace). Please post the text of exception and call stack. This will help us to narrow down the cause of the problem and we will be able to propose a solution as soon as possible.


Many Thanks & Kind Regards,

Hello,

It looks like we made a mistake in fixing this bug. I have added a debug information in the hotfix, could you please run it again. Print the exception out.

I try to catch the error in the parsing. It may be caused by some special email address. Please download the dll for your usage.
