Sendmail and Ignoring MX

/etc/mail/service.switch

Busy for hours to troubleshoot a sendmail(Centos5.5) to find out
why it insists on trying to deliver mail directly to A record addresses
rather than via MX records. I was lucky that Peter documented
his solution in 2002 so I can use it 9 years later!

Thanks Peter!

I saw this command and wonder if I could have used it: echo '3,0 student@sub.domain.edu' | sendmail -bt
