CODE:

{snip}

def send\_mail(from, to, subject, mesg)

mesgstr = \<\<ENDMESG  
From: #{from}  
To: #{to}  
Subject: #{subject}

```
#{mesg}

```

ENDMESG

```
require 'net/smtp'
Net::SMTP.start("localhost") do |smtp|
    smtp.send_message mesgstr, from, to, subject, mesg
end

```

end

{snip}

send\_mail(“localhost”,“removed\_email\_address@domain.invalid”,“mongrel”,“mongrel”)

ERROR:

I hate to be rude, but why are you asking this (and on a Ruby mailing  
list none-the-less)? This isn’t a ruby question, and “Recipient  
address rejected: User unknown in local recipient table” is a pretty  
cut and dry answer. Make sure the mail server on your machine is  
properly setup for relaying, and if until to sort that out after  
checking that documentation/researching, ask the community for your  
mail server.

550 generally means a server-end error.  
You may refer the RFC 2821 items.

um. no. you didn’t even bother to google for the 550 SMTP code.  
pharrington was dead on when he called you on that.
