OK. Digging into this...

sendmail.m4 has the lines:

  define(`FAX_MAILER_PATH',`/usr/bin/faxmail')dnl
  define(`FAX_MAILER_ARGS',`faxmail -d -n -p 12pt $u@$h $f')dnl
  MAILER(`fax')dnl

proto.m4 has:

`R$+ < @ $+ .FAX. > $#fax $@ $2 $: $1 user@host.FAX', `ifdef(`FAX_RELAY', `R$*<@$+.FAX.>$* $: $>MailerToTriple < $F > $1 <@$2.FAX.> $3 user@host.FAX',

sendmail.cf has:

R$+ < @ $+ .FAX. > $#fax $@ $2 $: $1 user@host.FAX

If the To: header is: joe@222.fax.foo.com

creates a -d argument of: >joe<@2201.fax.foo.com.

changing the proto.m4 to:

`R$+ < @ $+ .FAX. > $#fax $@ $2 $: $1 user@host', `ifdef(`FAX_RELAY', `R$*<@$+.FAX.>$* $: $>MailerToTriple < $F > $1 <@$2> $3 user@host',

makes no difference....

Try changing that to:

`ifdef(`FAX_RELAY', `R$*<@$+.fax.foo.com.>$* $: $>MailerToTriple < $F > $1 <@$2.fax.foo.com> $3 user@host.fax.foo.com',
