When I try to send the email with invalid recipient like  
removed\_email\_address@domain.invalid I get following error 550 unknown recipient. I try  
to catch the error with begin and catch but error is not caught.  
Any idea

If you want to rescue an exception you need to use rescue, not  
catch( which is something rather different in ruby)

# Sorry I mean rescue but I type catch. My code is like this

begin  
UserMailer.deliver\_sent\_to\_friend(from,recipient, subject, message)

```
flash[:notice] = "Message sent."

```

# rescue flash[:notice]=“Message not sent” end

However problem persist.
