Do you have any documentation on the query or table scheme.
I tried to add to SOGo database "users" table multiple entries for the same user or multiple email addresses in email field separated with comma or comma delimited. It doesn't work.
The SOGo "users" tables is created a view of vmail.mailbox tables
https://docs.iredmail.org/sogo-centos-6-mysql.html
https://sogo.nu/files/docs/v2/SOGoInstallationGuide.pdf

This is what I found on internet, but still I not managed to list multiple sender addresses in SOGo

Thanks man, that is helpful.
Based on your provided documentation this is the DB:sogo Table:aliases.
I can't the "aliases" table scheme documentation. Could you please share the required fields (names).

e.g. users:
+------------+--------------+------+-----+---------+-------+
| Field      | Type         | Null | Key | Default | Extra |
+------------+--------------+------+-----+---------+-------+
| c_uid      | varchar(255) | NO   |     |         |       |
| c_name     | varchar(255) | NO   |     |         |       |
| c_password | varchar(255) | NO   |     |         |       |
| c_cn       | varchar(255) | NO   |     |         |       |
| mail       | varchar(255) | NO   |     |         |       |
| domain     | varchar(255) | NO   |     |         |       |
+------------+--------------+------+-----+---------+-------+
CREATE VIEW sogo.users (c_uid, c_name, c_password, c_cn, mail, domain) AS SELECT username, username, password, name, username, domain FROM vmail.mailbox WHERE enablesogo=1 AND active=1;

Hi,

Thanks for support but this option is totally different from what I'm looking.
It will give aliases (address book) additionally from Global Address Book.

What I'm looking is sender email address + assigned aliases.
this is related to MailFieldNames.
Originally it configured: "MailFieldNames = (mail);"
what I'm looking for is something like this:  "MailFieldNames = (mail, aliases);"

If you know how the actual configuration should look like please share you knowledge.

The mysql table "forwardings" is created in "vmail" database.
In the "forwardings" table I have all the alias names filed to forward email to email address.

But I cannot get those aliases reflected in SOGo sender drop down menu.
Here I have added attachment from SOGo delegate mailbox option.
I want to get same drop down from active aliases.

I understand that I need to tweek (or mysql query or sogo config) question is how and/or where to find the guidlines.

I tried to play with MailFieldNames by adjusting mysql and adding aliases colmns. Still not managed to make it work.

If you have any advice and/ot guidlines I will be more then thankful for all your support

To help with SQL. How the columns should look like.
Currently my SQL is:
CREATE VIEW sogo.users (c_uid, c_name, c_password, c_cn, mail, domain) AS SELECT username, username, password, name, username, domain FROM vmail.mailbox WHERE enablesogo=1 AND active=1;

Please advise which column names and values I should create/adjust in order to see multiple aliases selection (sender) in new message
