returned and check that for a standard structure thing and see if it extends onto multiple lines. If so, there is always a size sent out, so have this function scan past that size and then look for the end tag. Since I don't have the time to delve into IMAP structure to get this done perfectly, I just do a cheap hack to scan to see if there is at least one more character incoming from the IMAP server. Maybe if I have time, I'll tackle this further.
