Good morning, I have a client that sends and receives e-mails only through the roudcube webmail, currently he tries to send e-mails through this webmail, but the webmail will not always display the message "sending" today I did a test I disabled the mod_securit of the server and was sent his emails right! In my configuration I have the mod_securit and plugin installed!
Server = apache + comodo rules and plugin+ php fpm!
