sendmail error in logs

[tctlrd]

Could someone explain this to me? This is from the snikket-server:dev logs.

sendmail: cannot connect to localhost, port 1025: Connection refused
sendmail: could not send mail (account default from /etc/msmtprc)
anacron: Tried to mail output of job `cron.daily', but mailer process (/usr/sbin/sendmail) exited with status 75

I did not see anything in the docs about sendmail or port 1025.
