[AlarmEmailFailedEvent] Alarm 'Host connection failure'

[sameerdave]

Hello,

i recently upgraded to the version 5.5 from 5.0.3 on scom sp1.
Now I am seeing loads of errors on my collector server -- "[AlarmEmailFailedEvent] Alarm 'Host connection failure' on esx.xyz.com cannot send email to abc@xyz.com"

Not sure what this means but these are our production servers, and wanted to find a resolution asap..

Thanks
Sameer

Thanks for your quick response.

We found the issue, and it was due to our VC servers blocking port 25. After opening the port, everything looks fine.

thanks
Sameer
