Does anyone have a general idea of what the traffic usage should be if an average of 1000 text emails are sent per day, in GB per month?
well, if it’s a 3k email, then
3x1000 = 3000k = ca. 3mb
3mb x 30 days = 90mb / month
Pretty much, it is hard to guess, if they like to send attachments it could be 10GB or more 
Yes this is what I had thought all along, but since there are no attachments and known mail sent is avg. of 20kb, it is hard to beleive that traffic of 41.3GB could be acheived in just 22 days with the amount of mail logged as sent. 2GB overnight last night.
This is a PHP autoresponder script using PHP Mailer.
I have found a security issue regarding PHP Mailer here:
www.securityfocus.com/bid/24417/info
I have opened a ticket #FGX-72484-377,
however Deepek doesn’t seem to think there is much that can be done from the JH side. I’m thinking, why?
Prehaps they have a 100MB message or so stuck in queue and each time they are online it is attempting to send?
I have not seen it personally but I saw stats such as this at the psoft forums where another hpshere customer saw this happen to a client
Well anything is possible, but I loaded all the messages myself and all are about 15 to 25mb each. Messages are sent when someone opt’s in from a remote form or sent out once every day or two or three via cron job or manual broadcast. All sent emails are counted. Only one user, plus me, has access to the broadcast feature. There are less than 10 (5 active) users and no autoresponder user account sends out more than 100 messages per day.
I was specifically talking about outlook/outlook express having a mail stuck in queue.
