Fine-tuning client behavior #

The Smtp, Imap and Pop3 objects makes it possible to adjust various client settings and workarounds. Most of them are available through Settings property (see the next section for details).

Some settings are available at the Smtp, Imap and Pop3 objects themselves. This includes the Encoding property that specifies a charset to be used when encoding commands and decoding responses. However, since all of those should normally use ASCII, changing the default value is seldom needed.

CSharp

// create POP3 client instance
pop3 = new Pop3();

// set encoding to UTF-8
pop3.Encoding = Encoding.UTF8;

VisualBasic

' create POP3 client instance
pop3 = New Pop3()

' set encoding to UTF-8
pop3.Encoding = Encoding.UTF8

The common settings include a Timeout property as well. Use it to change the default timeout value of 60,000 miliseconds.

Workarounds for common server issues #

Workarounds for some server issues are not enabled by default because detecting them automatically would be troublesome. They can be changed through properties of Smtp.Settings, Imap.Settings and Pop3.Settings objects.

CSharp

// create POP3 client instance
pop3 = new Pop3();

// ignore invalid message headers
pop3.Settings.IgnoreUnparsableHeaders = true;

VisualBasic

' create POP3 client instance
pop3 = New Pop3()

' ignore invalid message headers
pop3.Settings.IgnoreUnparsableHeaders = True

List of common tweaks and workarounds:

Object Property Purpose
Imap
Pop3
IgnoreUnparsableHeaders Ignore unparsable headers when parsing mail message received from the POP3 or IMAP server.
Imap
Pop3
IgnoreUnparsableSignatures Ignore unparsable S/MIME signature entities when parsing mail message received from the POP3 or IMAP server.
Pop3 DisableGmailRetrieveWorkaround Disables workaround for non-standard behavior of POP3 Gmail's RETR command.
Pop3 DisableApopAuthentication Explicitly disables APOP authentication for those POP3 servers, which falsely advertises APOP support.
Smtp AllowNullSender Allows null sender (<>) to be specified in Smtp.Send call. Used when sending delivery status notifications.
