When keying a new subscriber from the “newsletter page”, I experience few invalid address like following (I changed name’s letters) :
lzejzs.lbifer@univ_pau.fr although, I have several people with the address @univ_pau.fr
and few others email with accented letters are told invalid as well.
I run newsletter 7.6.7, I disabled antibot, akismet, antiflood and captcha
blog charset set is UTF-8 Database Charset is utf8mb4. As I experienced this problem, I “tried tables upgrade” without success.
Any idea of how I could fix this ?
