Hi,
I have SP 2013, and it was working properly. and workflows send emails perfectly. yesterday, i decided to build a fresh site collection so i deleted the old one and created a new one. now, workflows are unable to send emails. i'm sure it has nothing to do with my mail server cuz no changes happened to it. i'm sure about the settings for outgoing mail on central admin. all i did, was to enter mail server IP in outgoing mail field and email below it.
in the workflow status the status says "error" followed by this message: "The e-mail message cannot be sent. Make sure the outgoing e-mail settings for the server are configured correctly."
Any help please?
