Hi,

I have found the problem. Number of sent Mails has exceeded 500

@dj_steve

do you think your server could handle something like 2000 e-mails a day? Since this app has just started, i bet it might become more popular soon and people will start testing, specially when I improve somethign again

Let's say that currently it was sent 500 e-mails in about 5 hours, so 100 e-mail in 1 hour with attachments in average 20kb is actually only 2MB/hour, could you handle it on your server?
