gsmtp163.google.com.: No route to host mx4.mail.yahoo.com.: No route to host This is the msg I get from the maillog. I cant send or receive mails from my server. I can telnet :25 to it from anywhere: intranet and outside the lan. So I dont think it is the firewall... I have read tons of howtos and configure my sendmail in diferent ways, but I keep havinf the same problem... Now, geez I am so confuse that I dont know where to start!! Any ideas?
