Hello,
We are a medium sized business (about 40 users), and we have one user that sends out a weekly e-mail to about 300-400 recipients, it's a newsletter. This e-mail is about 1.5 megabytes per person (PDF file). Sometimes when she sends this, I notice our DSL line (3.5down, 800k up) is maxed out, transmitting at 800 constantly (We have a second internet connection as well that the exchange server does not sit on, for general surfing, so we can still access the net). I check the exchange system manager, and in the queues area, I see lots of domains listed with a "retry" status, and upon searching for messages in these queue's, they are all hers.
If I freeze all the queues, the data transmission continues, if I press "Disable outbound mail", it also still continues, but if I go to protocols, smtp, highlight my default smtp queue, and hit stop, then the bandwidth falls back to normal. If I start it again, bandwidth usage immediately goes back to max.
I am assuming messages are getting stuck in the queue somehow, she is not getting any NDR's, and this all happens within a few minutes of her sending it. Sometimes she will send these late in the afternoon after I've left, and when I check the logs in the morning, the DSL line has been maxed out the entire night (16 hours).
The badmail and other mail folders are empty on the server. I have tried going queue by queue within the smtp (there is a separate queue for each domain she is sending too), and deleting the messages from her, but this is very time consuming with 300+ messages, and I don't even know if that is doing anything or not.
So far the only way I've found to fix this, is to stop the virtual SMTP server, and to create a new virtual smtp server, and then mail proceeds normally, but anyone else's mail that was waiting in the old queue now is gone.
Any ideas? We're moving her mailings onto our lyris list soon so it won't be a problem, but I'd like to have a solution incase this happens again with another of our users.
Thanks.
