SendMail 8.14.x | CentOS 5.x
I've noticed that if I manually update /etc/mail/sendmail.mc (for example, enable TLS support), and then bounce sendmail, I get the following error:
Shutting down sm-client: [ OK ] Shutting down sendmail: [ OK ] Starting sendmail: sendmail.mc:18: m4: cannot open `/usr/share/sendmail-cf/ostype/linux-gnu.mf': No such file or directory [ OK ] Starting sm-client: [ OK ]
This only happens one time after I update a sendmail.mc file. If I bounce sendmail again (without making any other change), I don't see the error any more.
Any idea why this happens? It doesn't cause any errors - I'm just curious.
