Connecting to mail2b.geo.yahoo.com. via esmtp... Well, resolver got the MX records for geocities.com and this is strange that U couldnt connect to any of mailexchangers. Could U tcpdump ur telnet on 25 port to any of them using domainnames and IPs that I supplied below: mail.geocities.com internet address = 209.1.224.30 mail.geocities.com internet address = 209.1.224.29 mail.geocities.com internet address = 209.1.224.139 mail.geocities.com internet address = 209.1.224.42 mail.geocities.com internet address = 209.1.224.138 mail.geocities.com internet address = 209.1.224.44 mail??.geo.yahoo.com internet address = 206.251.17.77 (last 4 have the same IP). > > bootymasta@geocities.com... Host unknown (Name server: > mail2b.geo.yahoo.com.: host not found) Well, now U should check ur resolver&bind configuration. If U run local bind U have to have /etc/resolve.conf smth like this: domain ur.isp.domain.name nameserver [127|10|192|177].0.0.1 195.64.229.1 if no local bind- just: domain ur.isp.domain.name nameserver 195.64.229.1 then use nslookup to query ur bind and check answers. for this purpose man nslookup will help U. > > <dan@alphamale.ab.ca>...
