I implemented a loop over the whole 220/250 response parsing block, automatically continueing if status followed by - for identifying a multiline response. Now I additionally added a size validation for the response to avoid crashes when referencing into QByteArray by brackets operator using index [3]. Size checking for index [4] is obsolete since bytearray is trimmed and would result in early exit otherwise.
