This may be what you want:
while ( <LOG> ) {
if ( /user (\S+)\Q...\E$/ and my $user = $1 and
<LOG> =~ /Mail retrieval failed, reason: POP3 Host did not
acknowlege password and returned following error: -ERR [AUTH] Invalid login/ )
{
push @dup_array, $user;
}
}

No need to define %saw in file scope:
my @no_dup_array = do {
my %saw;
grep !$saw{ $_ }++, @dup_array;
};
