Well, if you have hand-modified your sendmail.cf instead of building it
from a .mc file with m4, or have some rewriting rules embedded in the
.mc, the most likely cause is that you have made an error in the rules
causing an infinite rewrite recursion.

Another possibility, if you have a m4-built sendmail.cf but are using
the virtusertable feature, is that you have a virtusertable entry like:

<something>  user@domain

where 'domain' is in class w. This will cause the result of the virtuser
lookup to be looked up again, with the potential for causing an infinite
loop. The general rule is to only use simple unqualified usernames in
the RHS of the virtusertable, unless it refers to a "remote" domain.
