	Hi,

	We are using the Mail-DLL for downloading Emails. But in the new Version, we have an Exception:

	[code]15.08.2014|08:34:04,544|ERROR|System.ArgumentOutOfRangeException: Argument is out of range of valid values. It must be in a range from 1 to 2147483647.

	Parameter name: messageInboxIndex

	Actual value was 0.

	at ComponentPro.Net.Mail.Pop3.DownloadMailMessage(Int32 messageInboxIndex)

	at supplierportal.FetchMail.getMailsPop3()|| [/code]

	We use the code from your Example (http://www.componentpro.com/doc/mail/Downloading-a-message-Synchronously.htm), but pop3Message.MessageInboxIndex is always 0.

	Is there a workaround for downloading the Email ?

	 

	Our code:

	[code lang='c#']

	           Pop3MessageCollection list = new Pop3MessageCollection();

	            try

	            {

	                list = client.ListMessages(Pop3EnvelopeParts.Size | Pop3EnvelopeParts.UniqueId);

	            }

	            catch (Exception ex)

	            {

	                _log.Error("Could not download Emails. Error: ");

	                _log.Error(ex);

	                throw ex;

	            }

	          

	for (int i = 0; i < list.Count; i++)

	 {

	                Pop3Message pop3Message = list[i];

	                // Download the message to an instance of the MailMessage class.

	                MailMessage Email = null;

	

	                try

	                {

	                    Email = client.DownloadMailMessage(pop3Message.MessageInboxIndex);

	                }

	                catch(Exception ex)

	                {

	                    _log.Error("DEB_FM_033_1: Fehler beim Email runterladen !");

	                    _log.Error(ex);

	                    continue;

	                }

	               .........

	

	                  

	

	                }

	                else

	                {

	

	                    if (_log.IsDebugEnabled)

	                        _log.Debug("DEB_FM_033: Email ist null, konnte nicht gespeichert werden");

	                }

	                

	 }

	            client.Disconnect();

	[/code]
