Many programmers and news admins have outlined the weaknesses of yEnc.<ref name="opponents">{{cite web |url=http://www.yenc.org/opponent.htm |title=Opponents to yEnc |first=Jürgen |last=Helbing |date=2002-06-10 |website=yenc.org |archive-url=https://web.archive.org/web/20130828001711/http://www.yenc.org/opponent.htm |archive-date=2013-08-28 |url-status=live }}</ref><ref>

For example, yEnc requires the strings "=ybegin" and "=yend" to be placed around the encoded file in the message body.<ref name="KimSchneider2010"/> Although this is an improvement over uuencode's "begin" and "end", which occur more frequently in normal text, message readers can still encounter the strings outside of attachments (most frequently in discussions about yEnc itself).  yEnc {{cns|date=February 2019|and uuencode|reason=Isn't file splitting outside of the scope?}} also attempt to reassemble files split into multiple messages by using the subject line, which is unreliable.{{according to whom|date=February 2019}}
