Issue Mailserver not working after install postfix

[HeRiNo]

Plesk 12.5.30 Update 44
Linux 6.8 Final

Hello, I installed postfix, that blocked plesk and I had no more access. Thaks for the help on this forum I can login Plesk again. I still can't install Postfix probably because of tjis:

/usr/sbin/postconf: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
)

So I installed Qmail and Dovecot. But still no mail. iI ran:

[root@vmi66617 ~]# /usr/local/psa/admin/sbin/mchk --with-spam
==> Checking for: mailsrv_conf_init... ok
==> Checking for: mail_handlers_init... ok

==> Checking for: mail_outgoing_restore... ok

and in /usr/local/psa/var/log/maillog I only see this:

I hope someone can help m with this. Oh I also ran: plesk repair mail and the outcome was:

Repairing the mail server configuration

What was the output of...

# ldd /usr/sbin/postconf

Is libmysqlclient.so.16 listed?

 

[HeRiNo]

No,
libmysqlclient.so.16 => not found

Well, on my CentOS 7.2 test VM I have...

# rpm -q --whatprovides /usr/lib64/libmysqlclient.so.18
MariaDB-shared-10.0.26-1.el7.centos.x86_64

I'm not familiar with CentOS 6.8 or its packages, but looking around it looks like you need to install this...

https://rpmfind.net/linux/RPM/centos/6.8/x86_64/Packages/mysql-libs-5.1.73-7.el6.i686.html

Check with...

yum whatprovides "*libmysqlclient.so.16"

And install...

# yum install mysql-libs

I hope that helps
Kind regards

Lloyd

Hello lloyd, you advice me to do 2 downloads. I tryed to do both and bot I got the same outcom:

Package mysql-libs-5.5.50-34.el6.art.x86_64 is obsoleted by mysql-community-libs-5.7.14-1.el6.x86_64 which is already installed
Nothing to do
[root@vmi66617 ~]#

And the outcom of yum whatprovides "*libmysqlclient.so.16" is in attachements.

Best regards, Herman.
