Thanks everyone for your help. A few points to close this one out. - regarding overloading the email server - that was one of my earlier concerns so I disabled all but one of the sending devices - it only sent an e-mail once every hour or so. - I did reboot the ISY - that allowed it to work intermittently (where before it was solid failure) - Having done nothing to my network or the ISY, it is now sending e-mails reliably Since it stopped working with no changes on my part and has now starting working again with no changes on my part, I'm assuming some sort of network issue. At least until it happens again

Yes - I've verified the setting on several other devices on the same network and it does work with the ISY occasionally. It started working sporadically when I set the timeout to its max. value. I periodically notice similar delays/issues on other mail systems.

I am using the smtp server for my local ISP. here is the error message I am getting: Thu 2014/09/04 06:14:12 PM System -50001 -5 I'm thinking there may be a problem with my ISP - I re-booted the ISY and the 1st test failed, the 2nd worked and the 3rd failed. I set the timeout value to the max. I've also tried with my smtp.gmail.com using my personal account.

I have a ISY994i Pro - it worked perfectly until a week ago - then e-mails stopped working. I've verified the settings on other devices on the same network and all is working well. Now, when I do the "Test", I get "server not responding". Previously, when working on this, I also received "Could not open file [/CONF/CACERTS.CFG]" and simply "Mail server failure [Connection Failed]" What can I look at to try to debug this issue?
