Please stop assuming that everybody will use your system immediately. Even if your system wins out eventually, there will be many years where a significant portion of the email users don't use it. Also you must assume that there will be competing systems. So maybe the WSR will adopt a system where subaddresses are constructed with '+' as a delimiter, and AON will use one where subaddresses are constructed with '-' as a delimiter.

Which would be unacceptable, given a company policy that everybody should have an email address of the form <firstname.lastname at domain> and the number of Peters around here. > Now back to original question: How will a mailing list handle this? > Well, obviously both peter.holzer at wsr and peter.janecek at wsr must > register for the same mailing list.

How do you deactivate an address which isn't even subscribed? Add a special blacklist? Yet another special feature to maintain (for both the software author and every mailing list operator). I expect that mailing-list software authors will not implement any special support for subaddresses, and even if they do, mailing-list operators will disable it, because it causes them trouble and they think that it's the users' job to get their mail-address right, not the operator's job to handle lots of special cases. hp -- _ | Peter J.
