Hi Gustavo,


Thanks for your advice and URLs.


A small database is running on Guest01, the mail server for routing,
with following tables created.


mysql> SHOW tables;
+------------------+
| Tables_in_maildb |
+------------------+
| aliases          |
| domains          |
| transport        |
| users            |
+------------------+
4 rows in set (0.00 sec)


mysql> SELECT * from domains
    -> ;
+------+-----------------------+-----------+---------+
| pkid | domain                | transport | enabled |
+------+-----------------------+-----------+---------+
|    1 | localhost             | virtual:  |       1 |
|    2 | localhost.localdomain | virtual:  |       1 |
|    3 | domain01.com           | virtual:  |       1 |
|    4 | domain02.com  | virtual:  |       1 |
|    5 | domain03.com  | virtual:  |       1 |
+------+-----------------------+-----------+---------+
5 rows in set (0.00 sec)


All incoming mails arriving on Guest01 are redistributed to the
respective mail servers according to domains.


I found following document on Internet;

Perdition
https://we.riseup.net/debian/perdition

POP3/IMAP Proxy Perdition mit MySQL backend
http://www.mth-solutions.de/howtos/postfix_und_co/perdition


Are they relevant for my application?  An example will be easier for me
to understand configuring perdition.  TIA
