-v option.
Are you invoking
sed with more than one file? Can you provide a more realistic example?

mkimapdcert
MKIMAPDCERT(8) Double Precision, Inc. MKIMAPDCERT(8)
NAME
mkimapdcert - create a test SSL certificate for IMAP over SSL
SYNOPSIS
/usr/sbin/mkimapdcert
DESCRIPTION
IMAP over SSL requires a valid, signed, X.509 certificate. The default location for the certificate file is /usr/lib/courier/imapd.pem.
mkimapdcert generates a self-signed X.509 certificate, mainly for testing. For production use the X.509 certificate must be signed by a
recognized certificate authority, in order for mail clients to accept the certificate.
/usr/lib/courier/imapd.pem must be owned by the daemon user and have no group or world permissions. The mkimapdcert command will enforce
this. To prevent an unfortunate accident, mkimapdcert will not work if /usr/lib/courier/imapd.pem already exists.
mkimapdcert requires OpenSSL to be installed.
FILES
/usr/lib/courier/imapd.pem
X.509 certificate.
/etc/courier/imapd.cnf
Parameters used by OpenSSL to create the X.509 certificate.
