Comment (by riasat):

 WP v4.6.1

 My nginx conf server block:


 {{{
 server {
         listen         80;
         server_name    ~^(?<subdomain>.+?)\.(?<domain>.+)$;
         root  /var/www/$subdomain;
         include conf.d/server_block_common.cnf;
 }

 }}}

 This is what I always get:

 {{{
 Fatal error:  Uncaught phpmailerException: Invalid address:
 wordpress@~^(?<subdomain>.+?)\\.(?<domain>.+)$ in
 }}}


 I know I can fix it by using "wp_mail_from" but I still don't get it why
 you can not simply default to "wordpress at site-domain.come" or even just
 give an OPTION in settings to set the SEND FROM field. It is ridiculous
 that people have to resort to code if they want to change wordpress
 portion of the SEND FROM field.
