Object reference not set error when retrieving IMAP data.

[rkarina94]

Hi,

I'm using the MailSystem.Net library for a Bounced Email tracking system that I'm working on.
Firstly, I initiate an IMAP connection to GMAIL servers with ConnectSsl() using port 993.

It runs well but after a few hours, this error occurs:

"Error:Object reference not set to an instance of an object., Stack Trace: at ActiveUp.Net.Mail.Imap4Client.Command(String command, String stamp, CommandOptions options)
at ActiveUp.Net.Mail.Imap4Client.Command(String command, CommandOptions options)
at ActiveUp.Net.Mail.Imap4Client.GetMailboxes(String reference, String mailboxName)
at ActiveUp.Net.Mail.Imap4Client.SelectMailbox(String mailboxName)"

when I try to retrieve the email data from the GMAIL mail servers with this method -
m_imapClient.SelectMailbox("NAMEOFFOLDER"). Any help would be great, thanks.

Regards,

Adhy
