Hi there,
I'm contacting you as I am running through a serious problem I can't figure out.
I'm able to receive mails, to send plain text mails and to send HTML mail if content is plain text.
Whenever I'm editing something (underline a text, put a bullet etc), I cannot send the mail. It is sending it till timeout and nothing happens... I'm pretty sure it used to work some times ago but it ain't anymore. Haven't changed a thing in roundcube config or postfix or dovecot. I have upgraded ubuntu some weeks ago though to version 18 beaver.
Do you have any idea what I should correct ?
found it !!!
it came from the mod_security in apache2 blocking html injection... Therefore my new question : is there a way that rouncude and mod_secure coexists. I like the sql injection and other feature protecting the server. Having to switch it off might prove risky in long run !
Could you provide the error message?
