Redmine

Hi,

I've configured redmine to accept incoming emails to create tickets. The rake task that I am running as a cron has the password for the receiving email entered as plain text . Instead can I use an encrypted password ? or is there any other method to securely give password ?

eg:
rake --trace redmine:email:receive_pop3 RAILS_ENV="production" host=my.mail.com port=110 username=fin@mydomain.com
password={encrypted-password} project=myproject allow_override=tracker,status,description,priority,assignee,category
