Avoid force-encoding display names that fit within qcontent
When the display name contains an At sign, or anything of the sort,
libvmime would forcibly encode this to =?...?=, even if the line
is fine ASCII which only needs quoting.
rspamd takes excessive quoting as a sign of spam and penalizes
such mails by raising the score (rule/match: TO_EXCESS_QP et al.)
