dict: Error: Fatal error in defaults handling. Program aborted

[Hugo Manuel Ojendiz Lemus]

Good day to everyone

 

Currently, I'm trying to implement the sieve "vacation" plugin with the
sieve "Extdata" plugin to lookup information from a MySQL remote server. I'm
following the instructions in the documentation:
https://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extdata

 

===== I have the following error ===

Apr 09 13:46:51 mail dovecot[5512]: dict: Error: Fatal error in defaults

============================

 

An important bit of information it's that the dict service was trying to
read the /etc/my.cnf file, but SELinux prevent it, and the sieve script
worked fine, once I solved the SELinux access problem, the errors began to
appear.

 

This is a postfix server working great for years, with a local MariaDB.

 

The remote MySQL server it’s in the same LAN and It’s reachable by the mail
server and other servers, the account has access, and like I’ve mention,
before I gave access to the local /etc/my.cnf the sieve script worked fine
(just the SELinux warnings). 

Looks like the dict service has problems with the local MariaDB
configuration file, but in this scenario it’s not required

 

Any information or help you can provide me would be greatly appreciated.
