Hello ladies and gentlemen.
There is a program on the basis of postfix+dovecot, with mysql screwed and what point I was somewhat frustrating — the user's display name when sending a message.
If you are using a mail client it's simple — the display name is set when creating accounts and all is well, but if the same user suddenly needs to send email via the web interface — it is necessary to specify in the settings web interface that is not convenient and as it is not correct, because almost accounts are created with postfixadmin and there when creating the specified user name. Question: whether it is possible to use the default username assigned when created in postfixadmin? or at least use it if not specified any name, because all these data are available from the database.
