When it comes back up you can keep SMTP primary. <DIV dir=ltr align=left>I'm not sure how to effectively check the "network" to see if SMTP is available, on one hand it seems straight forward but when I think about details it does not seem so obvious. My SMTP path looks something like this:</DIV> <DIV dir=ltr align=left> </DIV> <DIV dir=ltr align=left>Nagios -> local sendmail daemon -> smtp smarthost -> corporate smtp gateway -> corporate internet connection -> internet</DIV> <DIV dir=ltr align=left> </DIV> <DIV dir=ltr align=left>Maybe it's overkill to worry about all of those pieces but in my paranoid (i.e. mad boss wanting to know why we didn't know about a major outage) mind I don't want to leave anything out :-)</DIV> <DIV dir=ltr align=left> </DIV> <DIV dir=ltr align=left>Honestly I'm not checking all of those things now, but I would like to be a bit more thorough on the new setup, some of those things I don't have access to be able to check them.</DIV> <o:p></o:p> <o:p> </o:p> > How come you have to dial up each time to send alerts? That's a good question, that's just the way it worked when I first set it up and I did not check for another or better way. <o:p></o:p> <o:p> </o:p> <o:p></o:p> </DIV></BODY></HTML>
