MIME::Lite 包升级后在命令通道错误上抛出意外的 EOF
MIME::Lite throwing unexpected EOF on command channel error after package upgrade
我在 Windows 2008 服务器上使用 Strawberry Perl (v5.16.3)。我添加了一些用于脚本的 CPAN 模块,但这似乎已损坏 MIME:Lite(此框上的其他脚本使用了它)。当我运行以下代码时:
use strict;
use warnings;
use v5.16;
use MIME::Lite;
my $msg = MIME::Lite->new(From => 'person@domain.com',
To => 'person@domain.com',
Subject => "testing",
Type => 'multipart/mixed');
my $dataString = "Trying to figure out why this isn't working.\r\n";
$msg->attach( Type => 'TEXT',
Data => $dataString);
$msg->send('smtp', 'mailhost.com', Debug=>1);
我收到以下错误消息:
MIME::Lite::SMTP>>> MIME::Lite::SMTP
MIME::Lite::SMTP>>> Net::SMTP(3.10)
MIME::Lite::SMTP>>> Net::Cmd(3.10)
MIME::Lite::SMTP>>> Exporter(5.67)
MIME::Lite::SMTP>>> IO::Socket::INET6(2.69)
MIME::Lite::SMTP>>> IO::Socket(1.34)
MIME::Lite::SMTP>>> IO::Handle(1.33)
MIME::Lite::SMTP: Net::Cmd::_is_closed(): unexpected EOF on command channel: at d:/strawberry/perl/site/lib/MIME/Lite.pm line 2877.
SMTP Failed to connect to mail server: Bad file descriptor.
我在 Email::Simple、Email::Sender、Email::MIME::CreateHTML 和 String::Util 中安装的模块。我相信您知道,还安装了各种依赖项。
我只想将脚本切换到 Email::Sender,但服务器出现 421 错误(这又是一个谜)。我可以通过 telnet 连接到邮件服务器并获得 'HELO' 没有问题。
我担心 Perl 安装现在全部被顶起,但我希望你们中的一位聪明人可能对如何修复它有一些见解。
在此先感谢您的帮助。
编辑:我注意到 perl/lib 中的 Socket.pm 已更新。这可能是导致问题的原因吗?我将 MIME::Lite 更新到最新版本(版本 3.030),但这并没有解决问题。
编辑 #2:根据 ikegami 的回复,将打印语句添加到 NET::SMTP:
sub new {
print "inside Net::SMTP::new\n";
my $self = shift;
my $type = ref($self) || $self;
my ($host, %arg);
if (@_ % 2) {
$host = shift;
%arg = @_;
}
else {
%arg = @_;
$host = delete $arg{Host};
}
print "checked for SSL.\n";
if ($arg{SSL}) {
# SSL from start
die $nossl_warn if !$ssl_class;
$arg{Port} ||= 465;
}
my $hosts = defined $host ? $host : $NetConfig{smtp_hosts};
my $obj;
$arg{Timeout} = 120 if ! defined $arg{Timeout};
print "set timeout: $arg{Timeout}. \n";
foreach my $h (@{ref($hosts) ? $hosts : [$hosts]}) {
print "host: $h, port: $arg{Port}, laddr: $arg{LocalAddr}, lport: $arg{LocalPort}, familyKey: " . ( $arg{Domain} || $arg{Family} ) . "\n";
$obj = $type->SUPER::new(
PeerAddr => ($host = $h),
PeerPort => $arg{Port} || 'smtp(25)',
LocalAddr => $arg{LocalAddr},
LocalPort => $arg{LocalPort},
$family_key => $arg{Domain} || $arg{Family},

and last;
}
print "$obj\n";

print "object defined. \n";

Net::SMTP::_SSL->start_SSL($obj,%arg)

$obj->autoflush(1);
print "set autoflush.\n";
$obj->debug(exists $arg{Debug} ? $arg{Debug} : undef);

my $response = $obj->response();
print "object response: $response (5 == CMD_ERROR)\n";
unless ($obj->response() == CMD_OK) {
my $err = ref($obj) . ": " . $obj->code . " " . $obj->message;
$obj->close();
$@ = $err;
print "returning because response was not CMD_OK\n";
return;

returning because response was not CMD_OK

所以,它返回的原因似乎是 $obj
的响应是 CMD_ERROR
。它发送给 $obj=$type->SUPER::new
的唯一参数是主机。 (这是正确的主机,但我不得不在上面将其空白)。
所以,我不确定这是在调用哪个超类。它似乎从 NET::Cmd 返回常量,但没有 new
子例程。 IO::Socket:INET 从 IO::Socket 调用新的,从 IO::Handle 调用新的,似乎在调用 fdopen C 代码?我在这里有点迷路了。但是,感谢您到目前为止的帮助。看来我们几乎要找到问题的根源了。
Net::SMTP 版本 3.x 添加了对 SSL 和 IPv6 的支持。如果安装了必要的包(即 IO::Socket::IP 或 IO::Socket::INET6),它将使用 getaddrinfo 来解析通常优先使用 IPv6 优先于 IPv4 的名称。
如果一切设置正确,这不是问题。但在您的情况下,即使没有邮件服务器侦听 IPv6 地址或防火墙阻止连接,邮件服务器的主机名也会解析为 IPv6 和 IPv4 地址。因此导致连接失败,因为 getaddrinfo returns 应该使用 IPv6 但服务器无法通过 IPv6 访问。
正确的解决方法是删除主机的 IPv6 记录或使其可通过 IPv6 访问。只要不是这种情况,就可以通过在 Net::SMTP:
中明确强制执行 IPv4 来解决该问题
