"mr_mischief" beat me to the punch whilst typing, but File::Find works to return full pathnames of files in a directory without the need for chdir, readdir, or opendir. Then you can stat, move etc., using those full paths. Of course, you already have the pathname! so i don't understand why you need to chdir anyway (eg. won't "for my $file (<$src/*.imap>) work?), but here's a File::Find demo to consider: 

#!/usr/bin/perl
use strict;

use File::Find;

my @dirs=("/home");
my @files=();
                    
sub dirscan {
        if ($_ =~ /.imap$/) {push @files,$File::Find::name}
}

find(\&dirscan, @dirs);
foreach (@files) {print "$_\n"}

Positive thinking leads me to believe it will be faster.
