I have observed, in distribution lists like this one of mutt for example, when a big number of messages are deleted at the same time with D, the administrator of the list unsuscribes you due to an excessive rebound. It happens even with already read messages.
With other mail clients, If you first read or open the message and then delete it, regardless of the number of deleted messages no rebound issues are found. But with mutt, the option D seems to be interpreted as unread and deleted message, causing a rebound. Mutt is my favourite and daily email client, but to clean read messages from lists, I usually enter other client, mark as read and delete the messages. It is not a big problem, but I would like to understand the reasons and find a solution to delete messages without rebounds. Thank you all, and have a nice day. -- ---------------- Daniel GutiƩrrez
