how can i search contents of Email?
my code
Imap client = new Imap();
client.Connect(_ServerName, _port, _securityMode);
client.Authenticate(_seletedUserName, _seletedPassword);
client.Select("INBOX");
// I want to sarch "test" Keyword on Mail server
ImapCriterion criteria = ImapCriterion.Keyword("test");
ImapMessageCollection listMessages = client.ListMessages(ImapEnvelopeParts.UniqueId | ImapEnvelopeParts.Size, criteria);
It does not work well.
