I hadn't, but doing so achieved no change.

No errors reported (well, nothing at all reported, so presumably no errors!)


I've got some sort of fix, albeit one I'm not entirely happy with, and which 
isn't entirely working.  I've gone through master.cf and taken everything out 
of chroot operation.  

That has solved things to the extent that mail is now leaving the machine - 
albeit I don't understand why it stopped in the first place.

However, now it doesn't get accepted by the receiving host:

<david at familyaldred.org.uk>: host server4.sohoservers.net[82.113.133.69] said:
    553 5.1.8 <david at main.familyaldred.org.uk>... Domain of sender address
    david at main.familyaldred.org.uk does not exist (in reply to MAIL FROM
    command)

Aaargh.....  presumably I could get round this by renaming the machine as 
familyaldred.org.uk (which does have an MX address), though in many ways I'd 
prefer not to (as it fouls up a number of internal things on the network!).


Back to that chroot issue.   Am I understanding this correctly: postfix 
changes the root (/) location to one 'inside' its own directory structure, 
and looks for all it needs there?  If so, it seems to be missing a lot of 
libraries - and again I simply don't know what happened to the system that 
was working!

Could it be permissions somewhere?  In the /var/spool/postfix directory, ls 
-la returns

[root at main postfix]# ls -la
total 72
drwxr-xr-x  18 root    root     4096 Sep 12 17:53 ./

(It complains if etc is not owned by root).   

Still struggling.....
