Are you sure ? When I modify the .cf, I need to compile the .mc file as 
sendmail only know this one.
So the .mc file contains my modifications at this time. You see ?

I understand that it's unsupported, of course. I just wondered if it was 
not an option in yum, maybe...

Yes, but the 5107 and 5108 are based on Scientific Linux and it's 
problematic for some clients, convincing them to use CentOS instead of 
RH was already complicated, so Scientific Linux.... I know that you had 
already have this remarks and that you are working on the CentOS6 
release, right ?

If it's so, I suppose there is no possibility to just install the 
"base-*" files from 5607 or 5608 on this boxes, by modifying the yum 
repos, and keeping the PHP5.3 installed ?

The servers where the webUI was broken was 5106, but was up-to-date 
(redhat-release say "5.8"). Do you mean that the files are updated but 
always for a version 5.1 of PHP ? Do you maintain 2 branches, for PHP 
5.1 and PHP 5.3, of the UI ?
To be clear about the problem described, I haven't *moved* the admserv 
directories, but *copied* them in another location. So the updates of 
"base-*" have been applied in the original directories. When the files 
php.ini and php.conf were replaced, the pathes returned to these 
directories, and then admserv restarted with the installed PHP : 5.3.8, 
but in error.

About that, can you tell me if the prices given on Solarspeed for 
example are a definitive prices, or a yearly (monthly ?) rental ?
