Hi all again: Sorry, I'm fairly new to Sendmail although I've been playing around with it for a while. Where can I change the processing interval of the mail queue as well as expiration of mails in the queue? Also, may I ask if someone could point me to a good tutorial Web site about the m4 and its directives used to create the sendmail.mc file, which will in turn create the sendmail.cf file?
