I don't know why vCenter server cannot provide email notification directly to SMTP server at outside. so far since 5.5 till 6.5, they don't develop.
even i have gmail or office 365 hosting at outside, i do require to have SMTP relay on local.
my question is if my office 365 using port 587 not default 25, how can vCenter Server aware about this. because there is no option to put port of smtp server in vCenter configuration. there are only two box to complete. one is mail server (local ip address of smtp relay), and mail sender (email account of outbound email).\\
plz help to inbox to vmware to develop an option to point directly to outbound email.
