BTW: The server is in the Amazon EC2 cloud but I don't think it matters. Still, if I try a telnet on port 25, the connection opens faster from my office (ADSL) than from the Amazon VM. EC2 should be fast enough. How many users are on the list?
Ca. 500 users. It is an announcement lists only. .. I am surprised by the slowness. I wonder whether Amazon is throttling SMTP traffic.
Yes: Dear EC2 Customer, You recently reached a limit on the volume of email you were able to send out of SMTP port 25 on your instance: Instance ID: .. In order to maintain the quality of EC2 addresses for sending email, we enforce default limits on the amount of email that can be sent from EC2 accounts. If you wish to send larger amounts of email from EC2, you can apply to have these limits removed from your account by filling out our online request form. Okay, will see, how it goes. Maybe Amazon isn't the right place for it. Regards Peter
Linode has worked well for me in the past. Also I'm currently running a medium size mail server on hetzner.de. A 500 member list is nothing compared to that server. -- My blog http://etbe.coker.com.au Sent from a Galaxy S3 Android phone with K-9 Mail.

http://aws.amazon.com/ec2/#pricing A "small" EC2 instance costs 6 cents per hour or $43.80 per average month. Plus costs for bandwidth and storage. A "micro" instance costs 2 cents per hour or $14.60 per average month. A small image has 1.7G of RAM and 160G of local instance storage (which isn't suitable for things like list archives). A micro instance has 613M of RAM and only EBS storage (which is suitable for list archives etc but costs). https://www.linode.com/ A Linode 1GB instance has 1G of RAM, 24G of regular disk space, and 2TB of data transfer per month. It costs $20 per month and there are no extras. The cheapest Linode instance isn't going to be much more expensive than a micro instance from Amazon once you include the extras. It will be a lot cheaper than a small EC2 instance. http://www.hetzner.de/en/hosting/produktmatrix/rootserver-produktmatrix-ex Hetzner has a range of servers starting at E49 per month. The E49 server has 16G of RAM and 2*3TB SATA disks. If you get more IP addresses (E8 per month for 6 addresses and cheaper if you want more) then you can run Xen on the server and share access with your friends. This can make it a very cheap option. EC2 is really good for dynamically scalable systems and for situations where you need bulk computing off-peak (as demonstrated in a LUV talk some time ago). It's not particularly good for running a single server. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

There are also the reserved instances which costs a lot less if you want a server for a multiple of 1 or 3 years. A small instance for three years, Heavy utilization (for always on server; means you pay for every hour even if server is offline) is $257 + $0.012 per Hour. http://aws.amazon.com/ec2/pricing/#reserved A year ago I got on the three year reserved plan for $300 + $0.013 per hour. I seem to be paying $10.80 a month (+300/36 = 8.33 or $19.13 a month total), which includes 10GB storage. They did stuff up the original order however (they charged me but didn't give it to me) so check everything carefully to make sure you get the rates you expect. Looks like the rates have gone down slightly since I started. Only complaint, would be nice if EC2 offered native IPv6 support. Last I checked they don't, and a quick glance at Google suggests that is still the case. Brian May
