For SMTP you first have to establish a TCP connection to port 25 of the server in the usual way. POP3 is the same, but uses port 110. You only start talking SMTP or POP3 after these have been established. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
