Change outgoing Email settings in SharePoint 2013

I have configured Outgoing Email settings in SharePoint 2013. But the FROM email id in the mail shows another Email ID, what actually I have configured in Outgoing Email settings in SharePoint Central Admin.

Root Cause :

    The web application which triggers the mail has different email ID what we configured in the SP Central Admin.

PowerShell cmd to check OutboundMailSenderAddress,

 (Get-SPWebApplication http://SPWebApp).OutboundMailSenderAddress

Check for both, web app and Central Admin URL.

Solution:

I have updated the OutboundMailSenderAddress mail address using SP Management Shell,

$webApp = Get-SPWebApplication "http://SPWebApp"

$webApp.OutBoundMailReplyToAddress = "no-reply@suglog4.net"

$webApp.OutboundMailSenderAddress = "sharepoint2013@suglog4.net"

$webApp.IncomingEmailServerAddress = "suglog4Mail"

$webApp.Update()

Note : If you have more than one WFE and APP server run the above script line for all the servers and check whether the OutboundMailSenderAddress user has updated.

Now check the both the SP Central Admin and  Web App OutboundMailSenderAddress user's are same.

PowerShell cmd to check,

 (Get-SPWebApplication http://SPWebApp).OutboundMailSenderAddress
