MFA email timeout

MFA email timeout

Is there a way  to extend the timeout for sending the 2 factor authentication email to more than 30 seconds?  I have contacted support and they attempted add a smtp timeout line to the wrapper.conf file and it still times out in 30 seconds.  We are having issues with sending to 1 domain where sometimes it takes longer than 30 seconds and it times out and brings them back to the login page and they cant enter the code they receive.  I have contacted support and uploaded logs but it has been almost a week and I'm still waiting and kind of need a solution.
