Main fau mailservers are being incrementally upgraded to fix a bug. Impact should be minimal as most mail clients will retry and get a working mailserver. The mail hostnames that may be affected are as follows: smtp.fau.edu, smtpxy.fau.edu, bertx.fau.edu, berty.fau.edu, boc22esa02.fau.edu, nwesa02.fau.edu
We apologize for the inconvenience.
