(root) This happens when sendmail tries to generate a UUCP-style mail header line: "From <user> <date> remote from <host>" (see the 'U' flag in the mailer program description). Under this condition, sendmail wants an address of the form: <host!user>. Your configuration file probably produces the form: <user@host>. I ran into the same problem when I needed both From_ lines and <user@host> in locally delivered mail, and had to change two lines in some old sendmail source.
