[neomutt-users] Set all postings of a mailinglist to 'read'

[tuxic at posteo.de]

Hi,

is it possible to set all postings of a mailinglist to "read" without 
opening/list the mailinglist and without changeing the mailinglists
display settings?

If 'yes' - how can I accomplish this?

Thanks a lot in advance for any help!
Cheers!
