I’m using:

ruby 1.8.4 (2005-12-24) [i386-freebsd5]

I’m getting an error that I don’t understand when using Net::Smtp. This  
code  
works for most messages I’ve tried:

Net::SMTP.start(@smtp\_server, @smtp\_port, @helo\_domain) do |smtp|  
@users.each do |user|  
smtp.send\_message(mail.to\_s, mail.from.to\_s, user.email)  
end  
end

But fails with this error when some messages are sent (notably from  
Outlook,  
if that makes a difference):

/usr/local/bin/ruby18  
/usr/local/lib/ruby/gems/1.8/gems/Rist-0.0.1/bin/receive.rb  
/home/mark/lists/io-devel/". Command output:

I don’t know if this is a bug or something I’m doing wrong. Can anyone  
let me  
know what’s happening?

Thanks a lot,
