Hey! I followed this guide https://www.howtoforge.com/tutorial...php-pureftpd-postfix-dovecot-and-ispconfig/3/ Awesome I have to say. I have finished the instalation but now I'm facing a trouble and I dont now know to solve it. I have created from the ISPConfig a new inbox mail o mail account "buzon de correo" a new mail account. It seems to be ok but when i try to accesss from the roundcube interface it says "the username or the pasword is incorrect". I have trydeleting account, creating new one, changing password... I took a look to the phpmyadmin and i see that in the table users from roundcube db is empty nor like mail_user table from ISPConfig db that have the information stored. EDIT: I have checked that with doveadm user * that ispconfig doesn't create users in dovecot. [root@vps354795 ~]# doveadm user * nfsnobody vmail getmail ispapps ispconfig Greetings all.
