Setting up Sendmail to use SASL and TLS
Hi,
I've been having some serious problems with sendmail.mc. First of all could someone explain to me what dnl is? If something in the sendmail.mc is written: dnl # setting()dnl I presume that's commented out. So what if it doesn't have the #? Some settings have only dnl at the beginning, some at the end and some not at all - and this is from the default sendmail.mc!! If I can get my head around this, I can hopefully have a crack at setting it up propperly. Also, I can't find anything listening on port 25 from 'netstat'. Could anyone tell me why thats happening? I've just seen that a ps -ef shows the following: Code:
[root][/var/spool/mqueue]$ps -ef | grep sendmail |
dnl stands for delete to new line - it's the comment symbol for mc files. It means that m4 should ignore everything from the dnl to the end of the line. From memory, if you use the '#' symbol and have keywords in the comment, it can still get expanded.
And yes, having a load average of 17 will definitely stop mail delivery. I've seen my system stop at around 12 - did you have any problems running ps to even see that message? |
No, everything runs fine.
What is load average? I presume 17 is high? |
It's a guide to how hard your computer is working and is calculated as a function of processes waiting for the CPU. There's a more technical discussion of this at http://www.teamquest.com/resources/g...ay/5/index.htm, but if you want to watch it happening on your system try running the 'top' and 'uptime' commands.
