可以根据发出entry的 iDate, iDescription, iDetails这三个进行查找，你先保存发出entry的iDate, iDescription, iDetails或其中的一个，下面给你贴出遍历的代码：

TMsvId oldContext = iServerEntry->Entry().Id(); // save current entry id

User::LeaveIfError(iServerEntry->SetEntry(KMsvRootIndexEntryId));

CMsvEntrySelection* sel = new (ELeave) CMsvEntrySelection;
CleanupStack::PushL(sel);
User::LeaveIfError(iServerEntry->GetChildrenWithMtm(KPkiSmtpTechnologyTypeUid, *sel));

TInt count = sel->Count();
for(TInt ii = 0; ii < count; ii++)
{
User::LeaveIfError(iServerEntry->SetEntry(sel->At(ii)));
TMsvEntry entry = iServerEntry->Entry();
// check entry
}
CleanupStack::PopAndDestroy(sel);
User::LeaveIfError(iServerEntry->SetEntry(oldContext)); // resume old entry id
