I use an smtp site to send email generated from asp pages.<BR>However, a recent IP change by my ISP has been giving me problems.<BR><BR>I have it set to send me an email if there&#039;s a problem and content of those messages are the following:<BR><BR>Connection to **some domain** with Ip Address xxx.xxx.xxx.xxx failed from **my server fully qualified domain** <BR><BR>And one of the following error messages:<BR>1. Server received Winsock error ICMP network unreachable.<BR>2. Server received Winsock error Host not found.<BR>3. Server received Winsock error Connection timed out.<BR><BR>Is this because the mail servers that I&#039;m trying to send to, do not recognize my domain?<BR>Any help would be greatly appreciated.<BR><BR>Thanks.
