Instead, feed them directly to sendmail (or its lookalike): $ sendmail -i your-address@example.com <sample-virus-simple.txt $ sendmail -i your-address@example.com <sample-virus-nested.txt $ sendmail -i your-address@example.com <sample-nonspam.txt $ sendmail -i your-address@example.com <sample-spam-GTUBE-junk.txt $ sendmail -i your-address@example.com <sample-spam-GTUBE-nojunk.txt $ sendmail -i your-address@example.com <sample-spam.txt # old sample $ sendmail -i your-address@example.com <sample-42-mail-bomb.txt $ sendmail -i your-address@example.com <sample-badh.txt To avoid difficulty of downloading this package through firewalls which check contents for viruses, these sample files are now no longer included as a plain text, but are contained in a bit-complemented tar.gz archive. Here is how to extract original files from the file sample.tar.gz.compl: perl -pe 's/./chr(ord($&)^255)/sge' <sample.tar.gz.compl | zcat | tar xvf -
