Based on the way redhat designs their init scripts, you would edit the file /etc/sysconfig/sendmail and change the QUEUE variable to the interval you require. Then restart sendmail. As for the expiration parameters (timeout) - please read /usr/share/sendmail-cf/README file and search for "confTO_QUEUERETURN". This will position you within the README file where all the timeout (TO_) parameters are listed. Add the ones you want to change to your /etc/mail/sendmail.mc file and then recreate your sendmail.cf file. Example: define(`confTO_QUEUEWARN', `4h')dnl define(`confTO_QUEUERETURN', `5d')dnl Steve Cowles -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
