Hi everyone, I don't know if anyone have experienced this problem yet but one of my user is intermittently getting the following error when she send an email to one particular email address: There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <xxx.xxxx.COM #5.5.0 smtp;554 Transaction failed > This problem is happening only on this user and is intermitent and only happen when sending to this particular receipient. Sometimes it works without problem. Any idea?
