There are times that you need to save raw email data in eml format<\/strong>.<\/p>\n

This tutorial shows how to use Mail.dll POP3 and IMAP clients <\/a> to achieve this goal.<\/p>\n

Note that we don’t need to parse the emails, so we aren’t using MailBuilder<\/em> class and IMail<\/em> interface.<\/p>\n

Samples provided use both POP3 and IMAP protocols and both C# and VB.NET.<\/p>\n

Save email using IMAP:<\/h2>\n

The code below will search for all the emails with specified subject and write all these emails to your c: drive.<\/p>\n

\r\n\/\/ C# code\r\n\r\nusing (Imap imap = new Imap())\r\n{\r\n    imap.Connect("imap.example.com");    \/\/ use ConnectSSL for SSL connection.\r\n    imap.UseBestLogin("user", "password");\r\n\r\n    imap.SelectInbox();\r\n\r\n    List<long> uids = imap.Search(\r\n        Expression.Subject("email subject"));\r\n\r\n    foreach (long uid in uids)\r\n    {\r\n        var eml = imap.GetMessageByUID(uid);\r\n        string fileName = string.Format(@"c:\\email_{0}.eml", uid);\r\n        File.WriteAllBytes(fileName, eml);\r\n    }\r\n    imap.Close();\r\n}\r\n<\/pre>\n
\r\n' VB.NET code\r\n\r\nUsing imap As New Imap()\r\n\timap.Connect("imap.example.com")    ' use ConnectSSL for SSL connection.\r\n\timap.UseBestLogin("user", "password")\r\n\r\n\timap.SelectInbox()\r\n\r\n\tDim uids As List(Of Long) = imap.Search( _\r\n\t\tExpression.Subject("email subject"))\r\n\r\n\tFor Each uid As Long In uids\r\n\t\tDim eml = imap.GetMessageByUID(uid)\r\n\t\tDim fileName As String = String.Format(@"c:\\email_{0}.eml", uid)\r\n\t\tFile.WriteAllBytes(fileName, eml)\r\n\tNext\r\n\timap.Close()\r\nEnd Using\r\n<\/pre>\n
Save email using POP3:<\/h2>\n
As POP3 protocol does not allow searching, the code below will write all emails to your c: drive. You can easily limit this to the specified uid.<\/p>\n
\r\n\/\/ C# code\r\n\r\nusing (Pop3 pop3 = new Pop3())\r\n{\r\n    pop3.Connect("pop3.example.com");    \/\/ use ConnectSSL for SSL connection.\r\n    pop3.UseBestLogin("user", "password");\r\n\r\n    foreach (string uid in pop3.GetAll())\r\n    {\r\n        var eml = pop3.GetMessageByUID(uid));\r\n        string fileName = string.Format(@"c:\\email_{0}.eml", uid);\r\n        File.WriteAllBytes(fileName, eml);\r\n    }\r\n    pop3.Close();\r\n}\r\n<\/pre>\n
\r\n' VB.NET code\r\n\r\nUsing pop3 As New Pop3()\r\n\tpop3.Connect("pop3.example.com")    'use ConnectSSL for SSL connection.\r\n\tpop3.UseBestLogin("user", "password")\r\n\r\n  For Each uid As String In pop3.GetAll()\r\n\t\tDim eml = pop3.GetMessageByUID(uid)\r\n\t\tDim fileName As String = String.Format("c:\\email_{0}.eml", uid)\r\n\t\tFile.WriteAllBytes(fileName, eml)\r\n\tNext\r\n\tpop3.Close()\r\nEnd Using\r\n<\/pre>\n
