Gmail POP3 not getting all messages in Java application

I have enabled POP3 settings for my gmail. I am able to connect to the POP3 store using my password in a Java app. I have around 10k messages in my inbox. When I call getMessages on the Inbox folder it returns only 280 old messages. When I call getMessages in a loop, every call returns me same messages. I also tried getMessages(start, end) but it does not return other messages than those 280. How do I retrieve the other messages? By default, GMail's POP3 and IMAP server does not behave like standard POP3 or IMAP servers and hides messages from clients using those protocols (as well as having

IMAP or POP3 server implemented in PHP

时光总嘲笑我的痴心妄想 提交于 2019-11-30 14:22:37
Is there any available implementation of POP3/IMAP server in PHP? I am handling my e-mail service using sendgrid . I am going to store the messages on my server using files/db/whatever and now I'd like to provide full POP3 or IMAP (preferable) access for my users to their mailbox. Is there such implementation in PHP? Or is there any other possibility to run POP3/IMAP in the distributed environment of Windows Azure (assuming I have the mailboxes stored in shared blobs/tables/db)? Well, just to show that it is in fact possible to write a POP3 server in PHP, here it is. The server does no

电子邮件的工作原理 电子邮件是—种用电子手段提供信息交换的通信方式,是互联网应用最广的服务。通过网络的电子邮件系统,用户可以以非常低廉的价格(不管发送到哪里,都只需负担网费)、非常快速的方式(几秒钟之内可以发送到世界上任何指定的目的地),与世界上任何一个角落的网络用户联系。 电子邮件可以是文字、图像、声音等多种形式。同时,用户可以得到大量免费的新闻、专题邮件,并实现轻松的信息搜索。电子邮件的存在极大地方便了人与人之间的沟通与交流,促进了社会的发展。 工作原理 电子邮件的发送和接收 电子邮件在Internet上发送和接收的原理可以很形象地用我们日常生活中邮寄包裹来形容:当我们要寄一个包裹时,我们首先要找到任何一个有这项业务的邮局,在填写完收件人姓名、地址等等之后包裹就寄出而到了收件人所在地的邮局,那么对方取包裹的时候就必须去这个邮局才能取出。同样的,当我们发送电子邮件时,这封邮件是由邮件发送服务器(任何一个都可以)发出,并根据收信人的地址判断对方的邮件接收服务器而将这封信发送到该服务器上,收信人要收取邮件也只能访问这个服务器才能完成。 电子邮件的发送 SMTP是维护传输秩序、规定邮件服务器之间进行哪些工作的协议,它的目标是可靠、高效地传送电子邮件。SMTP独立于传送子系统,并且能够接力传送邮件。 SMTP基于以下的通信模型:根据用户的邮件请求

Pop3 to SMTP message custom forwarder in C#

戏子无情 提交于 2019-11-30 10:25:34
I'd like to write a service that periodically checks a POP3 account for new messages and based on custom business logic forwards the messages to an appropriate "To", and possibly changes the "From" as well. I might need to keep some messages on the server until certain conditions are ready for them to be forwarded. I found a sample using Chilkat .NET components that might work: http://www.example-code.com/csharp/pop3_forwarder.asp My question is: Are there any other examples of this in the .NET space using any other components? Thanks! f3lix The following SO questions/answers might help

retrieve email using c#?

会有一股神秘感。 提交于 2019-11-30 08:37:10
I want to retrieve emails from my Go Daddy account using C#. I tested OpenPop.NET to do that like so: OpenPop.Pop3.Pop3Client PopClient = new OpenPop.Pop3.Pop3Client(); PopClient.Connect("pop.secureserver.net", 995, true); PopClient.Authenticate("username", "pass"); My problem is that the server does not accept the user credentials. I'm sure the credentials are OK. I have tried the same code with my Gmail account and every thing goes OK. Is something missing that Go Daddy wants me to set? Is there another a .NET tool like OpenPop.NET that I can use to retrieve emails using the POP3 protocol?

Automatically check bounced emails via POP3?

大城市里の小女人 提交于 2019-11-30 06:55:48
Can anyone recommend software or a .NET library that will check for bounced emails and the reason for the bounce? I get bounced emails into a pop3 account that I can read then. I need it to keep my user database clean from invalid email addresses and want to automate this (mark user as invalid email). I have done a great deal of work handling bounce emails and there different types. If you want to be absolutely sure that the email your looking at is indeed a bounce of a specific kind I highly recommend getting a good filter. I have worked with Boogie Tools and it has worked very well. It lets
