NAME

smtp-source - multi-threaded SMTP/LMTP test generator

SYNOPSIS


        
    

    
        
            
smtp-source [options] [inet:]host[:port]

        
    

    
        
            
smtp-source [options] unix:pathname

        
    


        

    

    
        

            
                
DESCRIPTION

            
            
    
    
        
            
smtp-source connects to the named host and TCP port (default: port 25) and sends one or more messages to it, either sequentially or in parallel. The program speaks either SMTP (default) or LMTP. Connections can be made to UNIX-domain and IPV4 servers. IPV4 is the default.

        
    

    
        
            
Arguments:

        
    

    
        

            
-c

            

                
    
    
        
            
Display a running counter that is incremented each time an SMTP DATA command completes.

        
    


            

        

    

    
        

            
-C count

            

                
    
    
        
            
When a host sends RESET instead of SYN|ACK, try count times before giving up. The default count is 1. Specify a larger count in order to work around a problem with TCP/IP stacks that send RESET when the listen queue is full.

Don't disconnect after sending a message; send the next message over the same connection.

-o

            

                
    
    
        
            
Old mode: don't send HELO, and don't send message headers.

Send length bytes as message payload. The length does not include message headers.
