Question

使用Mail :: IMAPClient的任何代码都有此错误。要验证我已使用主题中的以下示例：How do I authenticate into Gmail using Perl?

#!/usr/bin/env perl -w
use strict; use warnings;
use Mail::IMAPClient;

# Connect to IMAP server
my $client = Mail::IMAPClient->new(
  Server   => 'imap.gmail.com',
  User     => $user,
  Password => $pass,
  Port     => 993,
  Ssl      =>  1,
  )
  or die "Cannot connect through IMAPClient: $@";

# List folders on remote server (see if all is ok)
if ( $client->IsAuthenticated() ) {
  print "Folders:\n";
  print "- ", $_, "\n" for @{ $client->folders() };  
};

# Say so long
$client->logout();

现在，我已经遇到类似这样的问题，但从未见过如“网络无法访问”这样的奇怪错误。没有实际的网络问题，ping工作正常。我安装了IO :: Socket :: SSL，Net :: SSLeay。

$ echo -n | openssl s_client -connect imap.gmail.com：993

CONNECTED(00000003)

Answer 1

这可能是一个ipv6错误。 Gmail最近启用了ipv6访问权限。你能尝试在“使用Mail :: IMAPClient”之前加入它吗？行：

use IO::Socket::SSL 'inet4';

Perl IO :: Socket :: SSL：connect：网络无法访问
