Question

I am using this piece of code (the port used is 995) :

Private Shared Function ConnectToPop3Server(ByVal pop3Obj As POP3, ByVal sslObj As SSL) As Boolean

        Utils.LogInformation(String.Format("Starting."))
        Try
            If My.Settings.UseSSL Then
                ' use SSL only if the configuration says so
                sslObj.CredentialVerification = CredentialVerification.None
                pop3Obj.Connect(My.Settings.EmailServer, My.Settings.IncomingPortSsl, sslObj.GetInterface())
            Else
                pop3Obj.Connect(My.Settings.EmailServer, My.Settings.IncomingPort)
            End If
            'Catch Easy Mail POP3 exception errors
        Catch POP3LicenseExcep As Quiksoft.EasyMail.POP3.LicenseException
            Utils.LogError("POP3 License Exception: " + POP3LicenseExcep.ToString()) : Return False
        Catch AuthExcep As Quiksoft.EasyMail.POP3.POP3AuthenticationException
            Utils.LogError("Authentication Exception: " + AuthExcep.ToString()) : Return False
        Catch ConnectExcep As Quiksoft.EasyMail.POP3.POP3ConnectionException
            Utils.LogError("Connection Exception: " + ConnectExcep.ToString()) : Return False
        Catch ProtocolExcep As Quiksoft.EasyMail.POP3.POP3ProtocolException
            Utils.LogError("Protocol Exception: " + ProtocolExcep.ToString()) : Return False
            'Catch parse exception errors
        Catch ParseLicenseExcep As Quiksoft.EasyMail.Parse.LicenseException
            Utils.LogError("Parse License Exception: " + ParseLicenseExcep.ToString()) : Return False
        Catch InputStreamExcep As Quiksoft.EasyMail.Parse.InputStreamException
            Utils.LogError("Input Stream Exception: " + InputStreamExcep.ToString()) : Return False
        Catch OutputStreamExcep As Quiksoft.EasyMail.Parse.OutputStreamException
            Utils.LogError("Output Stream Exception: " + OutputStreamExcep.ToString()) : Return False
        Catch ParseExcep As Quiksoft.EasyMail.Parse.ParsingException
            Utils.LogError("Parsing Exception: " + ParseExcep.ToString()) : Return False
            ' catch SMTP exceptions            
        Catch ex As Exception
            Utils.LogError("Exception: " + ex.Message + " - " + ex.StackTrace.ToString()) : Return False
        End Try
        Utils.LogInformation(String.Format("Finnished."))
        Return True

    End Function

which is basically following closely the samples provided with the library.
I am getting this when pop3Obj.Connect is called

Quiksoft.EasyMail.SSL.SSLConnectionException: Error receiving data from socket.  ---> Quiksoft.EasyMail.POP3.POP3ConnectionException: Error reading from stream. ---> Quiksoft.EasyMail.SSL.ᜀ: Unable to decrypt message.-2146893055

   at Calico.InboxMonitorService.Service.ConnectToPop3Server(POP3 pop3Obj, SSL sslObj) in C:\DefaultCollection\AlertCustomizations\Calico\WorkOrdersMonitor\Service.vb:line 205

Anybody that has experience with this package and can pitch in with some advice?

Answer 1

After finally getting in contact with Quiksoft it turned out that I have to update to the ver. 3.0.1.23 assemblies. All the Ssl connection errors disappeared.
