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
