I was getting messages like: Fetching with Net::FTP:  ftp://ftp.flirble.org/pub/CPAN/authors/01mailrc.txt.gzCouldn't fetch 01mailrc.txt.gz from ftp.flirble.org Fetching with LWP:  ftp://ftp.mirror.anlx.net/CPAN/authors/01mailrc.txt.gzLWP failed with code[400] message[FTP return code 150]Fetching with Net::FTP:   ftp://ftp.mirror.anlx.net/CPAN/authors/01mailrc.txt.gz First I tried removing the exisint Config.pm file from /usr/lib/perl5/5.8.5/CPAN/ Then I tried the install… Read more »

Using CentOS5/RHEL5 I needed to add some perl modules for SpamAssassin.

I then arrived at the CPAN prompt:  cpan>  install Mail::SPF::Query cpan>  install… Read more »
