Is sending email from EC2 / Rackspace Cloud a bad idea?
- by Michael Buckbee
In this article it mentions that TrendMicro is now treating all emails from Amazon's EC2 as coming from "Dial Up Users": likely to be spam and this is creating severe deliverability issues with their emails.
We're having all kinds of issues sending email from our app servers on Rackspace cloud (which may or may not be DUL'd) and I wonder if this isn't just a losing battle and we should try to get a different host for our SMTP server.
