That is not enough to diagnose. You should also post the next line lines in maillog with the same queue ID - MAA23626 - which will tell you what sendmail did with this particular email. The problem with rediff that sendmail reports here is that the IP (203.199.83.144) has a PTR entry, but the name doesn't have an A entry in DNS. So, sendmail thinks that the person who controls this IP is trying to forge emails to look like they are coming from rediffmail.com. Note that PTR record and A record are more often than not in different DNS servers hosted and managed by different people. It is quite natural for sendmail to assume that someone with access to the DNS server for 203.199.83.144 is trying to spoof himself as rediffmail.com (he typically wouldn't have access to the DNS servers of rediffmail.com). Using dig(1) to locate SOA records, we can find that the authoritative DNS server for the IP address 203.199.83.144 is dns.vsnl.net.in, but for webmail22.rediffmail.com is dns01.exodus.net. No wonder sendmail logged a warning.
