Hello RudiC,


Well, I managed to trim down the dataset with "sort -u input > output", but this will only remove pure duplicates. But still, running my script on this filtered dataset will take ages :/

I presume 'sed' could help me but I can't figure out what regex I should feed him..

NAME
setmaillist - create a binary mailing list SYNOPSIS
setmaillist bin tmp DESCRIPTION
setmaillist reads a mailing list from its standard input. setmaillist writes the mailing list in a binary format to tmp; it then moves tmp to bin. tmp and bin must be on the same filesystem. If there is a problem creating tmp, setmaillist complains and leaves bin alone. The binary mailing list format is portable across machines. setmaillist always creates bin world-readable. MAILING LIST FORMAT
The mailing list read by setmaillist is a series of lines. NUL bytes are not allowed. If a line begins with a dot or slash, setmaillist takes the entire line as an include file name. If a line begins with an ampersand, setmaillist takes the rest of the line as a recipient address. If a line begins with a letter or num- ber, setmaillist takes the entire line as a recipient address. Each recipient address must include a fully qualified domain name. Recipi- ent addresses longer than 800 bytes are not allowed. setmaillist ignores blank lines and lines beginning with #. It also ignores spaces and tabs at the ends of lines. For example, god@heaven.af.mil djb@silverton.berkeley.edu is a mailing list with two addresses. SEE ALSO
