Hi,

I’m having a problem with sending email with ActionMailer.

My mailer looks something like this:

class PNGMailer \< ActionMailer::Base

def forgotten\_password\_email (password\_reset, user)  
recipients = user.email  
from = “removed\_email\_address@domain.invalid”  
subject = “Password Change Request”

```
body :first_name => user.first_name, :last_name => user.last_name

```

end

end

I have checked a million times that recipients is set to a valid email  
address.

When I check my postfix logs, I get the following message:

warning: Illegal address syntax from localhost[127.0.0.1] in RCPT  
command: \<\>

It appears that somewhere down the line, I am losing the recipient email  
address.

Even more odd is the fact that this code works fine on my dev computer.  
Just not on my server.

Any ideas?

Thanks.

Sorry to bother, but it appears my problem has to do with needing it to  
be @recipients, not just recipients.
