To mark all messages sent to a specific bug report's address on mutt's bug tracking system as list mail, for instance, you could say -``subscribe [0-9]*@bugs.guug.de''. Often, it's sufficient to just +âsubscribe [0-9]*@bugs.guug.deâ. Often, it's sufficient to just give a portion of the list's e-mail address.
Specify as much of the address as you need to to remove ambiguity. For example, if you've subscribed to the Mutt mailing list, you will receive mail addressed to mutt-users@mutt.org. So, to tell Mutt -that this is a mailing list, you could add ``lists mutt-users@'' to your +that this is a mailing list, you could add âlists mutt-users@â to your initialization file.
