I do have root access. Brutal approach: Look in /var/mqueue/ In there, is mail waiting to be sent, it's in two parts (two files) per message. One file is the headers, the other is the message. The filenames have a few different characters to distinguish which part is which, at the start of the filename, and a long string of random characters common to each message, to indicate which two files go together for one message. Delete the two of them. I'd stop sendmail, first, so you don't have a fight with it. -- [tim@bigblack ~]$ uname -ipr 2.6.23.1-10.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5. Today, it's FC7. Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
