WeOnlyDo! COM ImapServer ActiveX control is component that can be easily integrated into your applications to provide full IMAP4rev1 protocol server implementation. All you need to do is to put it on VB form, call it's Start method and it's immediately accepting connections by your clients! It fully supports commands defined in RFC2060. Since wodImapServer is COM object and not the full application, there's few things developer should look after - simply because COM objects cannot deal with information that should be preserved between the sessions. Most important is to keep UID information (UNIQUE ID) for folders and messages. If you do so - wodImapServer will work flawlessly with any client that connects to it. On each client action wodImapServer will fire appropriate event where you can internally handle the action and return positive or negative result. You should also deal with message flags. wodImapServer does not deal with message storage - you should do it by yourself. It will deal with structures and references to folders and messages - but actual contents of messages cannot be handled by wodImapServer. Rather, it will depend on your code when messages are accessed, hoping that you provided properly formatted messages and proper flag information. If you don't - it will not complain, but IMAP clients may... You should consider all wodImapServer folder as virtual folders - none of them doesn't necessarily exist on your system. Each time wodImapServer requires list of folders, or list of messages - event is fired to notify you to populate his collections with appropriate information - and that's all. You can keep messages in database, on external system, or wherever you need - as long as you can provide necessary information on wodImapServer's request.

WeOnlyDo! COM Pop3Server ActiveX control is a component that can be easily integrated into your applications to provide full Pop3 protocol server implementation. All you need to do is to put it on VB form, call it's Start method and it's immediately accepting connections by your clients! It fully supports commands defined in RFC1939. Use your favorite mail client (such as Outlook Express or Eudora) to read mail provided by your own application. How? That's easy part: just put wodPop3Server control on your form, add some code around and it's all setup to be used. If you dislike adding additional code - it's fine by wodPop3Server. It will still work, and reject all the clients (with bad username/password error). But, if you add login capabilities using 'Connected' event (that's easy part - set Action = Allow for specific username/password combination). Still, if you want to make real Pop3 server application, look no more for native support for socket related material - you just found it. wodPop3Server will deal with clients and connections - you must deal with messages. Once new user logs on to your Pop3 server, you need to provide any kind of information about his mail. This is really easy task. If you keep all the emails in separate files, that's just great for usage with wodPop3Server. If you prefer to keep it in one large file - we will not argue about it. You can specify filename, starting and ending position for each email in mailbox, and WeOnlyDo! Pop3Server will pass it to remote client with ease. However, you might have some small problems maintaining such mailbox since sometimes it needs to delete messages, change status, etc.. But don't worry - it all can be done after user logs off.

Use your favorite mail client (such as Outlook Express or Eudora) to send mail to other users on your network . How? That's easy part: just put SmtpServer control on your form, add some code around and it's all setup to be used. If you dislike adding additional code - it's fine by Smtp. It will still work, and accept all emails but delete them immediately after user disconnects. But, if you define real filename on your disk, all the emails will be stored to that file. Still, if you want to make real Smtp server application, look no more for native support for socket related material - you just found it. Smtp server will deal with clients and connections - you must deal with messages. Once new user connects to your Smtp server, you need to provide some way of storing message posted by user to some file on disk, or just read it from Body property and store manually to, for example, database. This is really easy task. If you keep all the emails in separate files, that's just great for usage with WeOnlyDo! Smtp server. If you prefer to keep it in one large file - we will not argue about it. You can specify filename, make Smtp server Append to that file, and everything will still work just great. As a result, you will have one mailbox for each user just like on UNIX computers. Together with WeOnlyDo! Pop3 server, you can make powerful fully maintained mail service application that will share emails in your company, receive them from internet and anything else you can imagine. You can even create emails for your employees on the fly. You can make Smtp store to same files from where Pop3 reads them.
