Hello

I retrieve a number of message 1 to n  
And try to send these by stmp that is no problem with te following code  
:

```
 messages = Spool.find_created_messages

 Net::SMTP.start('sigma.itxl.nl',25,'itxl.nl') do | smtp |
   for message in messages
     begin
       smtp.send_message message.mime_content, message.email_from 

```

,message.email\_to  
message.destroy  
rescue Net::SMTPSyntaxError  
message.state = ‘ERROR’  
message.save  
rescue Exception =\> exc  
message.state = ‘ERROR’  
message.save  
STDERR.puts “General spool error #{exc.class} #{exc.message}”  
end  
end  
end

I would like to handel smtp errors gracefully, log the message en  
continue with the next message  
in the loop.  
For example when the email adres has a syntac error danielitxl.nl ( no  
@)  
The next message should be sended, so the system doesn’t get halted

Any ideas ?

Thanks in advantage

I have pinpointed the problem what happens is this :

daniel-wijnands-powerbook58:~/Desktop/mailing danielwijnands$ ruby  
script/runner ‘Spool.spool’  
General spool error Net::SMTPServerBusy 450 \<pietitxl.nl\>: User unknown  
in local recipient table  
General spool error Net::SMTPSyntaxError 503 Error: nested MAIL command  
General spool error Net::SMTPSyntaxError 503 Error: nested MAIL command

The problem is that i’m sending multiple messages.  
When te exception occurs ( Net::SMTPServerBusy 450 ) the server still  
has the message open.  
When i send another message it says Nested Mail command.

Is it possible to reset the connnection or the previous command ?

Okay i have a solution. but i think it could be formed nicer :

Net::SMTP.start(‘mailserver’,25,‘domain’) do | smtp |  
for message in messages  
begin  
smtp.send\_message message.mime\_content, message.email\_from  
,message.email\_to  
message.destroy  
rescue Exception =\> exc  
message.state = ‘ERROR’  
message.save  
smtp.finish  
smtp = smtp.start(‘domain’)  
STDERR.puts “General spool error #{exc.class} #{exc.message}”  
next  
end  
end  
end  
end
