I figure I would check here first. Some time ago, Dreamhost put anti-spam procedures into place so that shell scripts needed to use a real, fully-hosted return address to send anything out. I did that.
For months, I have been able to send email from form submissions and shell scripts. It still works, with one exception.
When sending some emails, I like to send myself an SMS using ATT's email to SMS gateway which is email@example.com. It has worked for years, but now none of my scripts are generating an SMS.
I went to my gmail account and sent an email directly to SMS. That went through fine. I think it's likely that ATT has put some type of filtering on it.
Does anyone else have this problem or a solution?
