what does ls -l sendmail.cf show? Has it changed recently? There should a default version of sendmail.mc you can compile and then substitute. If in doubt.

If it got changed you may want to revert. Here is how to revert:
sendmail.mc is what you change then compile with m4 into sendmail.cf. You did that, right? ...assuming you already changed something. It is not a good idea to edit sendmail.cf directly, BTW.

SENDMAILCONFIG(8)					      System Manager's Manual						 SENDMAILCONFIG(8)

NAME
sendmailconfig - configure sendmail for Debian systems SYNOPSIS
sendmailconfig [--no-reload] DESCRIPTION
sendmailconfig is used to simplify the configuration of sendmail(8) for use on Debian systems. In the simplest case, you may run this program to (re)configure sendmail for your Debian system at any time. It will modify the file /etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf. For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invokations of sendmailconfig will preserve these changes provided they are made at the end of the file. Normally sendmailconfig will ask if you want to reload sendmail after making changes to its configuration. The --no-reload option will avoid this question. FILES
/etc/mail/sendmail.mc sendmail m4 input to generate sendmail.cf /etc/mail/sendmail.cf actual sendmail configuration file /etc/mail/sendmail.cw names for which we will accept mail in the standard configuration /etc/mail/sendmail.ct names of trusted users in the standard configuration SEE ALSO
