I just upgraded a RHEL install this weekend to 4.0RC1, I have found that it doesn't always sync my email on my Treo 700p consistantly. For example, this morning, I work up, clicked Sync and it downloaded nothing (which is very odd). I logged on to my computer and I had about 15 messages. Then today, I was out and about, checking my email...no issue...then about 2 hours into my out of the office time it stopped getting any new mail. I figured it was possible that I didn't get any email, but when I got back to my office, I had about 10 emails (from that time period). Is this a known issue in the pre-release, I didn't see anything in bugzilla.
