Thinking it over again, I believe it will be enough to periodically 
(e.g. once a day or every couple of days or even less) sync only the 
data dir (vmail ---> vmail1) just to make sure we have updated users' 
settings and leave security_tokens enabled.

I can think of only one scenario which might cause problems: In case 
users are using vmail1 (due to inaccessibility to vmail) and during that 
time vmail gets live again (while users continue using vmail1) and 
happens that a cron job executes during this time and syncs the data dir 
(vmail ---> vmail1), could this data directory synchronization cause 
application problems to squirrelmail on vmail1 due to the fact that 
security token values in pref files on vmail1 will be overwritten (with 
those of vmail server)?

Please advise.

Thanks,
Nick
