From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5a) Gecko/20030728 Mozilla Firebird/0.6.1 Description of problem: Running Perl 5.8.0 Email::Valid v 0.15 and Email::Valid::Loose 0.02 on Redhat 9. Test code: #!/usr/bin/perl use strict; use warnings; use Email::Valid::Loose; my ($add, @adds); my $addrfile = $ARGV[0] || die "filename not given"; open (EMAILS, "$addrfile"); #remove troublesome windows /r characters #and whitespace while (<EMAILS>){ chomp $_; $_ =~ s/\015//; $_ =~ s/\s//g; push @adds, $_; } close (EMAILS); foreach $add (@adds){ #if email is invalid move on if (!defined(Email::Valid::Loose->address($add))){ print $add." is a bad address\n"; #address is bad }else{ print $add." is a good address\n"; #address is good } } Test file: user1@foo.com user2@foo.com user3@foo.com The error: Unrecognised line: user1@foo.com at /usr/lib/perl5/site_perl/5.8.0/Email/Valid.pm line 232 This code does work on Mandrake 8.1 (perl 5.6.1) Gentoo 1.4 (same versions as above) and Redhat 6.2.

Another description of the problem on an entire different setup: http://www.nntp.perl.org/group/perl.qpsmtpd/1226 Just for the record, the cause and solution: Mail::Address->parse($email) caused an the error (croaks): Unrecognised line: 'foo@mydomain.com' Well, it seems that perl 5.8.0-5.8.? has several problems with utf8. The internal representation of perl strings has an UTF-8 flag associated that can be turned off via Encode::_utf8_off($string), so a way to solve some issues like this are to use this workaround. (see Encode documentation for more details). I saw postings refering that the problem may be cause by using perl with thread support, which is not the case I tested it under perl with and without thread support with the same results. (The stock perl shipped with some distros are threaded enabled: e.g. RedHat 9, RHEL, WBEL...) A generic workaround to cases like this would be to use: Encode:_utf8_off($parameter_variable); before calling the problematic function, which in this case is Mail::Address->parse(). This has to be used with caution since it messes with perl internals, so sometimes you'll have to switch the flag on after calling the function.
Very sorry for the long delay in processing this bug report. This bug is no longer a problem with the perl in any current Red Hat OS.
