Hi Guiseppe.

I will recommend an upgrade of Centos (version 6 and then latest Qmail).
This I would do in another box or in a virtuel box to make sure the new Qmail is up running before shutting down the ol' one.

Centos 4.6 hasn't been maintained since back in 2012 or before so there may be a risk that some libraries may have been updated and therefore a qtp-sa-update may end bad.

You could try the sandbox feature in Qmailtoaster-plus if You are familiar with it (I'm not) and check if the update works - but this may also lead into difficulties if You haven't used that before (again new libraries etc..).

If possible at all, then make a new install of Centos 6.x (not version 7 yet), install Qmail using the latest procedure (yum).

Create a backupfile of Your mailboxes using qtp-backup from Your version and then using the backupfile and qt-restore on the new system - it should be possible.

Look at the qmailtoaster-list to check out how to install latest Qmail - there are many entries describing the commands to do it (Thanks to Eric 'Shubes' and others).


Hope this helps You on the way ahead.

Cheers,
Finn

Maybe an update could give you some security fixes.

vpopnmail-toaster5.4.17-1.3.4
vqadmin-toaster 2.3.4-1.3.3

There are about 1000 mailboxes

webmail does not work and the SMTP connection is rejected with error:

maybe I could use a good anti-spam spamdyke type, but are still not
sure, how do I do a bit of trabolsutting?

thank all
