Bug#392831: exim4-config: colons or semi colons as separators (debconf templates issue)

[Binzberger Viktor]

Marc,

Your 'fix' just caused us a few hours of clueless debugging. Using 
lsearch;/etc/mail/domains in dc_other_domains  is a very common method 
of implementing simple virtual domains. Now, with your update, our 
existing setup broke, and it just simply didn't occur to us, that the 
update script could be so stupid as to REPLACE the semicolons, instead 
of HALTING WITH AN ERROR (or a warning), which would be a reasonable 
behaviour in such situations.
