filtering afterwards

[Buba Mc Kraken]

hi guys,

i just thought i could finally make the jump from sylpheed to mozilla mail. so i configured my pop3 account with my 500+ mails. mozilla downloaded them all very nicely. then i created nice folders like:

mailinglist/xy
mailinglist/xyz
mailinglist/abc
...

then i made nice filters which should move the mails directly in the right folder. i marked all the 500+ mails in my inbox and then the search started... i couldnt find an option like "filter selected mails".

i rummanged every single option in my mozilla (Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.0.1) Gecko/20020928) but couldnt find such an option. did i miss something or is there really no such possibility to filter mails AFTER having them already downloaded?

sure i could make the filters before downloading the mails but why should i... i really miss that feature.

well again, did i miss something or is a feature like that planed in sooner versions?

thanks for the enlightenment
