Response to: What is purpose of 2nd sendmail session?
I get these errors if I am not running sendmail as a server on the box, but something tries to send mail to users on the box. Cron jobs try to do this if the job generates any output, and in my case all these crashes were related to cron jobs. This aspect of the problem can be solved by putting a line like:
at the top of cron files, where your_real_email_address is what you think it is. If the messages are innocuous and annoying the best way to deal with them is a mail filter rule that is very specific to the innocuous error message - that way, if your cron job ever runs into _real_ trouble, you will notice. This is better than simply redirecting all cron job output to /dev/null, at least for some things.
