邮件退信原因（Remote mail） 邮件退信原因(Remote mail) Daquan common mail bounce diagnostic analysis 2008, 01 Wednesday, 30 October, 09:59 A.M. < small tip: suggest you press Ctrl+F to call up the find toolbar, enter the key questions you want to query, and find your problems and solutions quickly and conveniently. > Often send messages to people may have the message returned has received were returned to the mail should be analyzed in return letters generally have a brief description, combined with these instructions you can further understand the specific reasons and make corresponding processing, this paper will analyze the bounce. One, by which the contents of the message The bounce is the automatic reply by the transceiver system, so the letters are English content, let us first understand what are included in the message. The message sender is generally Mail Administrator (system administrator), the theme of letters is generally Returned like Mail sentence. The upper end of the bounce bounce indicates the reason: Invalid User, Connection time out... Etc.... The central content of the bounce time, user name and other specific information correspondence occurred. Letters which are not normally sent are usually attached to the end, so that you can take corresponding remedial measures in a timely manner. Two common reasons, bounce and Solutions 1, the email address is wrong If you have the following information of remote, please check the address of the recipient is wrong. 550... User unknow 550, Requested, action, not, taken:mailbox, unavailable 550.5.1.1 > is, not, a, valid, mailbox Sorry, no, mailbox, here, by, that, name 550 Invalid recipient > Xxx@xxx.xxx.xx.xx (user, not, found) If the email address is correct, the email address of the other party may no longer be used. In order to determine, then again in case is due to the other mailbox server failure recovery technology return. 2, mail space is not enough If one of the following information display in the remote mailbox, said overflow. 552, Message, size, exceeds, fixed, maximum, message, size (5000000) 552, Message, size, exceeds, maximum, message, size "Message size exceeds fixed maximum message size:5242880 bytes" This means that the other party's mailbox has been limited, and the remaining space is not large enough. Your letter has exceeded its capacity limit, and the other party has to return it. The solution is to "lose weight," such as compressing attachments, deleting unnecessary items, and then sending emails when the other party cleans up the mailbox. 3, the mailbox space is full The other mailbox capacity were limited, once the mailbox is full, the following information will appear in one of the reasons for bounce: User, is, over, the, quota 552... Mailbox, is, full 550... Can't, create, output 552, Requested, mail, action, aborted:, storage, allocation In this case, you only have to wait one or two days or notify your friends to delete (or take away from the server) old letters, and then send them again. 4, the mailbox settings error If your domain name is 263mail.com.cn remote in the following tips: 554, Too, many, hops, 27 (25, max): from, user@>263mail.com.cn, via, mail., firstdomain.com, to, sameuser@263mail.com.cn It means that you jump too much, this is because your letter arrived at the other party's A mailbox, because the A mailbox set up automatically forwarded to the B mailbox, and the B mailbox is set up automatically forwarded back to the A mailbox. As a result, your letter travels endlessly between the A mailbox and the B mailbox. It takes a long time to send the letter back to you. 5 、 send server fault If the remote: >: connect to xxx.xxx.xxx. XXX timed out Said the timeout error is mostly due to the side of the server at the same time received more mail, of course, these mail not spam mail at work, and you are so unable to send. This kind of problem won't bother for a long time. Just wait a moment and resend it. 6 、 the sending server is blocked If the reason for return: 554 >: Recipient, Address, rejected:Relay, access, denied It has nothing to do with the recipient. Generally, because of the problem with your server, it refuses to send the letter to this address for you. However, this problem is less likely to occur. 7, China GFW (Great FIRE WALL) the Great Wall gateway filtering The performance for the timeout, the connection loss, 'User not please' try local; Aaazzzaaazzzz... Such mail failures often manifest themselves as: (host alt1.gmail-smtp-in.l.google.com[64.233.167.114] Said: 551, User, not, local, please, try, lost, connection, with,, mx21.Forever21.com[65.125.176.131], while, sending, MAIL, FROM And mail content is replaced with: AAAAZZZZZAAAAZZZZAAAZZZZ This message is sent to overseas (including Hong Kong) mail in GFW automatic censorship and surveillance of Internet content is generated by the rebound, only when sending mail to overseas (including Hong Kong) happens, sent to the domestic EMAIL can not make such problems. The solution: the need to physically build overseas servers and to take encryption measures between overseas servers and domestic transmissions to circumvent international export problems. If there is no physical overseas server, or there is no effective encryption of mail transmission technology, fundamentally can not solve the problem of overseas mail transmission. At present, the domestic mailbox service providers, overseas server and encryption technology is mature, the most important 263 enterprise mailbox. 8, others In addition, the letters sent at one time are too large, resulting in a greater probability of failure to send. Therefore, if you have many attachments to send, you'd better send them into small mail. Three, common bounce message analysis highlights 1, prompt information: Sorry, I, couldn't, find, a, mail, exchanger, or, IP, address. (#5.4.4) The reason: failed to retrieve mail recipient domain name analytic (MX records) and DNS (A records). Solution: check the recipient domain name is valid, and the correct set of mail analysis (MX record) or domain name resolution (A records). Query command (DOS or command line prompt execution): Nslookup - q=mx delivery domain name 2, prompt information: invalid address (#5.5.0) or User unknown or user is not found The reason: not the recipient. Solution: please check that the other party's email address is correct, or have not changed. Generally mail address, please fill in the wrong parts of the front, please check it and send it to the other party. 3, prompt information: Sorry, I, couldn't, find, any, hostnamed, XXX.com. (#5.1.2) The reason: not the host. Solution: the general is the other email address @ the back part of the error, such as the @hichina.com in @hichian.com, there is also the other side may be a problem with the server or the middle line in question, if the name is checked, you can only let the other solution. , I'm, going, try, again, this, message, has, been, in, the, queue, too, long., not, to The reason: many attempts, but the mail cannot be delivered to the recipient. Solution: check whether the connection to the recipient mail server SMTP (Simple Mail Transfer Protocol) is normal. 5, prompt information: Sorry, I, wasn't, able, toestablish, an, SMTP, connection. (#4.4. 1)或者550系统繁忙。 退信原因:无法建立SMTP连接或者对方服务器忙。 解决办法:由于对方某一台收件服务器当时正处在繁忙之中造成的，请您重新发送，最好同一封信件发送两次，收到的几率应该大一些。 6、提示信息:连接到远程主机，但它不能像收件人。 退信原因:连接到接收方邮件服务器，但接收地址不存在。 解决办法:确认接收地址是否正确。 7、提示信息:连接到远程主机，但发送者被拒绝。 退信原因:连接到接收方邮件服务器，但投递地址被拒绝。 解决办法:一般是由于您的企业邮局所在服务器IP地址被国际反垃圾邮件组织列入黑名单，导致您发往某些地区的邮件可能被拒绝。对此我们非常抱歉和无奈，虽然wbwy提供的企业邮局系统有严格的反垃圾邮件策略，但仍有可能被列入黑名单，主要原因是由于我们某些用户，通过自己或其他一些服务商所提供的宣传邮件发送软件，发送了宣传自己网站的垃圾邮件，被国际反垃圾邮件组织发现，该类组织除了立即屏蔽发送垃圾邮件服务器的IP地址外，同时出于严格抵制垃圾邮件的原则，也会将其网站域名的DNS服务器、网站所在服务器、域名邮件交换(MX)指向服务器的IP地址都列入黑名单，导致同处一台机器的用户和中国wbwy被无辜牵连。不过，从以往的经验来看，经过我们和国际反垃圾邮件组织的积极沟通解释，一般此类无辜牵连的屏蔽都很快可以解除。出现此类问题，您可以通过登陆wbwy 网站会员区，通过在线问题提交的方式提供一下具体的退信内容(退信内容要求提供完整。应该包含完整的收发信人地址，发信时间，问题描述或错误信息等)，或是收发双方的账号及具体发信日期，由我们为您负责联系对方的邮件服务商商谈解除屏蔽的事宜，请您耐心等待或暂时使用其他邮局服务发送国外邮件。对此给您及贵司所造成的不便再次表示歉意，并希望能继续得到您的理解和支持，倡导大家遵守互联网行为规范，共同保护和维持互联网的美好环境～～～ 8、提示信息:连接到远程主机，但失败后，我发出的信息。 退信原因:连接到接收方邮件服务器，但发送邮件失败。 解决办法:一般是因为接收方邮件空间满了，或者接收方根据邮件附件、内容设置了拒收。可联系接收方检查调整其邮箱即可。 9、提示信息:552message大小超过限制。 退信原因:您发给对方的信件大小超过了对方允许的范围。 解决办法:原因是您的邮件太大，超过对方邮件大小限制，请减小后从新发送。 10、提示信息:接收方的邮箱已满(# 5.5.4)或者配额超过用户的硬限制 退信原因对方邮箱已满:。 解决办法:由于对方邮箱超过了允许的容量，您只能让对方清空邮箱后再接收。 11、提示信息无效:553人 退信原因:投递方发信地址伪装，被wbwy邮局拒绝。 解决办法:请投递方将邮件域名添加一条优先级较低的MX记录，指向头地方使用的SMTP服务器对应的IP地址;或者请投递方将SMTP服务器的IP地址设置反向解析。 原文连接:。 cn /博客/后/ 222.html =========================================================== ========= 邮件服务器错误大全 =========================================================== ===================== 400错误报告 问:421服务器太忙 答:因为收件方服务器问题无法连接，这是收件方服务器的SMTP会话全或者是因为收件方服务器交通无法进行新的SMTP连接请过一会儿重新发送，如继续发生错误时向收件方管理员咨询。 问:421微软ESMTP邮件服务，版本:5.0.2195.5600准备在服务不可用，关闭传输通道 答:收件方的微软ESMTP服务器无法正常工作引起的发送失败请过一 会儿重新发送，如继续发生错误时向收件方管理员咨询。 问:421 4.3.1非法从<< xxx@xxx.com >对不起。你的IP有问题。此连接将关闭。请发邮件给mailsysop@hanmir.com(用另一个邮件服务器)。谢谢您. 答:由于收件方地址错误引起的发送限制错误向显示的咨询邮箱地址发送邮件咨询IP。 问:421 4.3.2 IP(XXX，XXX，XXX，XXX)过滤，这种连接将被关闭。你必须登记你的IP spammaster@hanafos.com SpaceLee、邮件服务器的主 答:发送人的IP地址在www.hanafos.com的网址上登录为邮件引起的发送限制错误向显示的咨询邮箱地址发送邮件咨询垃圾邮件。 问:421 4.3.2 IP(XXX，XXX，XXX，XXX)过滤，这种连接将被关闭。你必须登记你的IP 。 答:发送人的IP地址在www.naver.com的网址上登录为垃圾邮件邮件引起的发送限制错误。请参考Naver。COM的垃圾邮件政策。 问:441 4.4.1没有回答主持人 答:收件方邮件服务器没有应答失败的连接请过一会儿重新发送，如继续发生错误时向收件方管理员咨询。 问:441 4.4.1临时DNS失败hanmail网> <。 答:连接hanmail。净的时候因违反hanmail。净的垃圾邮件政策引起的错误。请联系1544-0580分机2咨询 问:450,xxx@xxx.xxx >:收件人地址被拒绝:greylisted 300秒(见) 答:发送方的邮件地址在收件方的graylisting系统上已登陆并存在引起邮件发送延长的错误。 问:451 4.4.0 DNS解析错误 答:没有找到收件方的网址出现的错误。请确认现在邮件服务器拥有的DNS服务器是否正常运行可以试一下参考其他ISP的DNS发送邮件企业的。 问:451高其他或未定义的邮件系统现状 答:收件方邮件系统错误或连接的服务器并不是SMTP时发生的错误。 问:451 4.3.0临时系统故障。请稍后再试。 答:因收件方服务器的障碍无法收件的错误。 问:451 4.4.2连接不良(IO) 答:因收件方服务器应答时间超过断开连接发生的错误请过一会儿重新发送，如继续发生错误时向收件方管理员咨询。 问:451中继服务器没有准备好 答:收件方服务器的一系列功能没有正常工作引起的错误请过一会儿重新发送，如继续发生错误时向收件方管理员咨询。 问:452对不起，您的收件人地址不在我的本地列表 答:在收件方的邮件服务器里不存在所发送的地址。请确认收件人的邮件地址是否正确并且确认此地址是否在收件方实际存在的地址。 问:452 4.4.5请求的邮件动作中断:超出存储分配 答:收件方邮件服务器储存空间不够引起的错误。请向收件方管理员咨询。 问:452 4.4.5写磁盘/磁盘空间不足的错误发生 答:收件方邮件服务器储存空间不够引起的错误。请向收件方管理员咨询。 问:452 4.4.5磁盘空间不足;稍后再试 答:收件方邮件服务器储存空间不够引起的错误。请向收件方管理员咨询。 问:452 4.4.5邮箱或超过MessageQuota <电子邮件地址> 答:收件人的个人邮箱空间不够引起的错误。请向收件方管理员咨询。 ============================================ 500错误报告 问:你必须5xx垃圾邮件 答:发送方的邮件服务器网址或地址及邮件地址被收件方邮件服务器登陆为垃圾清单引起的错误向收件方管理员咨询请求从垃圾清单上删除IP。 问:5xx信封发件人列入垃圾邮件发送者 答:发送方的邮件地址被收件方的邮件服务器判定为垃圾邮件地址而引起的错误。向收件方管理员咨询请求从垃圾清单上删除。 q:500语法错误，无法识别命令 命令语中一些被漏掉或一些错误的命令语引起的错误AMTP。 q:500文件发送错误 答:传送邮件时因网络的障碍等原因而导致传送失败。 q:501拒绝域名 答:发送方的网址被收件方的服务器拒绝而引起的错误。 q:501个坏发件人地址表达式 答:发送人或收件人的邮箱地址错误引起的。请确认发送人的邮件地址是否正确。 问:缺少501个 命令语中一些被漏掉或一些错误的命令语引起的错误AMTP。 问:501 5.1.8发件人域必须存在< XXX公司> 答:收件方的xxx.com网址不存在而引起的错误。请确认收件人邮件地址中的网址是否正确。如地址正确请向收件方管理员咨询是否已登陆在实际网址相关的邮件服务器上。 q:503个命令序列错误 命令语中一些被漏掉或一些错误的命令语引起的错误AMTP。 问:504你注册为垃圾邮件 答:发送方的邮件服务器网址或地址及邮件地址被收件方邮件服务器判定为垃圾清单内的邮件地址而引起的错误向收件方管理员咨询请求从垃圾清单上删除IP。 问:504我们不接受邮件，垃圾邮件发送者。如果你有问题，请电邮 答:发送方的邮件服务器网址或地址及邮件地址被收件方邮件服务器判定为垃圾清单内地址而引起的错误向收件方管理员咨询请求从垃圾清单上删除IP。 问:511对不起，这里没有这个邮箱的名字(# 5.1.1 -头) 答:收件方的邮件地址在收件方的邮件服务器上不存在引起的错误。 Please make sure the recipient's address is correct.
