I upgraded to .4 from .3 the other day and I have one customer that uses webmail 100% of the time for his email. My other customers use it from time to time. He will click reply or be in the middle of sending an email and click send and it will come back with page not found. If he clicks back and clicks it again then it will work most of the time. I seen this first hand. The server also hosts a bunch of websites and never had issues or complaints with the rest. The same customer says his administration site for his website works just fine which is on the same apache server which really stumps me. Anyone else know whats going on or have the issue?
