In email readers is that if I can mark the messages to be deleted after a particular date/time. I use squirrel mail and gmail. As far as I know, both do not give such an option. More often than not, one likes to get rid of a mail, but not immediately. If at the time of reading, the message can be marked so, then, it would be available to me till that date and then will disappear. Are there any mail services which offer this facility?
