There are several different email headers that make email high priority<\/strong>.<\/p>\n

Most correct is Priority<\/em> header, but also Importance <\/em>is used.
\nOutlook uses X-Priority<\/em> header.<\/p>\n

Mail.dll email library<\/a> offers simple solution of this problem: PriorityHigh()<\/strong> method.<\/p>\n

The following code sends high priority email, that has all mentioned above headers set accordingly:<\/p>\n

\r\n\/\/ C# version:\r\nMailBuilder builder = new MailBuilder();\r\nbuilder.Subject = "This is important";\r\nbuilder.Html = "<html>....<\/html>";\r\nbuilder.From.Add(new MailBox("alice@mail.com", "Alice"));\r\nbuilder.To.Add(new MailBox("bob@mail.com", "Bob"));\r\n\r\nbuilder.PriorityHigh();\r\n\r\nIMail email = builder.Create();\r\n\r\nusing (Smtp client = new Smtp())\r\n{\r\n    client.ConnectSSL("smtp.example.org");\r\n    client.UseBestLogin("alice@example.org", "password");\r\n    client.SendMessage(email);\r\n    client.Close();\r\n}\r\n\r\n<\/pre>\n
and as usual VB.NET code:<\/p>\n
\r\n' VB.NET version:\r\n\r\nDim builder As MailBuilder = New MailBuilder()\r\nbuilder.Subject = "This is important"\r\nbuilder.Html = "<html>....<\/html>"\r\nbuilder.From.Add(New MailBox("alice@mail.com", "Alice"))\r\nbuilder.[To].Add(New MailBox("bob@mail.com", "Bob"))\r\n\r\nbuilder.PriorityHigh()\r\n\r\nDim email As IMail = builder.Create()\r\n\r\nUsing client As Smtp = New Smtp()\r\n    client.ConnectSSL("smtp.example.org")\r\n    client.UseBestLogin("alice@example.org", "password")\r\n    client.SendMessage(email)\r\n    client.Close()\r\nEnd Using\r\n<\/pre>\n
Using fluent interface:<\/p>\n
\r\n\/\/ C# version:\r\n\r\nusing Fluent = Limilabs.Mail.Fluent;\r\n\r\nFluent.Mail.Html("<html>....<\/html>")\r\n    .Subject("This is important")\r\n    .To("to@example.com")\r\n    .From("from@example.com")\r\n    .PriorityHigh()\r\n    .UsingNewSmtp()\r\n    .Server("smtp.example.com")\r\n    .WithCredentials("user", "password")\r\n    .WithSSL()\r\n    .Send();\r\n<\/pre>\n
\r\n' VB.NET version:\r\n\r\nImports Fluent = Limilabs.Mail.Fluent;\r\n\r\nFluent.Mail.Html("<html>....<\/html>") _\r\n    .Subject("This is important") _\r\n    .To("to@example.com") _\r\n    .From("from@example.com") _\r\n    .PriorityHigh() _\r\n    .UsingNewSmtp() _\r\n    .Server("smtp.example.com") _\r\n    .WithCredentials("user", "password") _\r\n    .WithSSL() _\r\n    .Send()\r\n\r\n<\/pre>\n
 PriorityLow()<\/strong> method is also available.<\/p>\n
It’s also really easy to check the email’s priority with GetGenericPriority<\/strong>.
\nGetGenericPriority checks Priority, Importance and X-Priority headers.<\/p>\n
\r\n\/\/ C# version:\r\n\r\nIMail email = new MailBuilder()\r\n    .CreateFromEml(imap.GetMessageByUID(uid))\r\n\r\nGenericPriority priority = email.GetGenericPriority();\r\nif (priority == GenericPriority.High)\r\n{\r\n    \/\/ Your code goes here\r\n}\r\n\r\n<\/pre>\n
\r\n' VB.NET version:\r\n\r\nDim email As IMail = New MailBuilder() _\r\n    .CreateFromEml(imap.GetMessageByUID(uid))\r\n\r\nDim priority As GenericPriority = email.GetGenericPriority()\r\n\r\nIf priority = GenericPriority.High Then\r\n    ' Your code goes here\r\nEnd If\r\n\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
