// Description:
// The sever contains and retrieves an email with an attachment (a v-card), the aim of th test is to check that this
// attachmenet is fetched correctly by comparing its size and centent to the size and content of the source file attached.
// 2. The client connects to the server, requests a sync and a populate
// 3. The server reads the protocol information from a file specified in the ini file (ImapAttachmentTest.ini).
// 4. The client disconnects.
// 5. The attachment of the mail fetched is compared with the corresponding source file. The test passes if its size and content is exactly the same as the size and content of the file originally attached to this email, otherwise itv fails.
// 
//
