Learn about spoofing<http://aka.ms/LearnAboutSpoofing> Feedback<http://aka.ms/SafetyTipsFeedback> Hello Friends, In UASG workshop today, we had a detailed recap and discussion on UA + EAI issues. During discussion, we agreed the following points to be discussed further and need resolution… 1. Sender ID as xn--anything in local part. If email server receives an email FROM xn--anything@validdomain , should email server at receiving end Do.. 1. the conversion of xn--anything to UTF8 string. [Mark Svancarek] IF you host the mailbox and IF xn—anything maps to a UTF8 mailbox that you already administer, and IF you have no mailboxes with xn—anything as the local part: then you may transform. But this is not an officially recommended practice. 1. Leave it the way it was received i.e xn-anything [Mark Svancarek] In all other cases, this is forbidden. The official guidance is don’t ever do it. UASG should not be accountable to spell out the very specific exception case I define above. 1. Is Mixing of scripts is allowed in mailbox local part While creating a mailbox like.. 1. scripta@scriptbdomain - ajay@ਡਾਟਾਮੇਲਭਾਰਤ<mailto:ajay@ਡਾਟਾਮੇਲ.ਭਾਰਤ> [Mark Svancarek] I don’t think there is any specific existing rule or even guidance on this example, for or against. I vote that UASG support this example. 1. scripta+scriptc@scriptbdomain ajayअजय@ਡਾਟਾਮੇਲ.ਭਾਰਤ<mailto:ਸੰਪਰਕ@ਡਾਟਾਮੇਲ.ਭਾਰਤ> [Mark Svancarek] We should recognize that the local part rules are very permissive and therefore this should be an ALLOWED case per the spec. But I vote that UASG declare it as a NOT RECOMMENDED case EXCEPT for script combinations which are already allowed to be mixed in the root zone. 1. Alias ID on MUA: We already agreed that Downgrading of Alias is good practice and to be followed by email servers while communicating with legacy systems , however we have not discussed how Alias will be made available on MUA and if there are many Alias, than which will be used for downgrading. [Mark Svancarek] I don’t recall this topic, and I don’t understand the question – sorry! Please clarify. Lets discuss. Thanks. Ajay.
