Bug#493526: exim4-config: mailname not automatically added to MAIN_LOCAL_DOMAINS

[Matthew Moore]

Package: exim4-config
Version: 4.63-17
Severity: important


Hello.

Let me say right off that this bug may have the same underlying cause as 481597, I'm not 
certain.

I dpkg-reconfigure'd exim4-config recently to set up for smarthost operation.  The problem I 
observed was that all mail was sent to the smarthost, even mail which should have been 
delivered locally, e.g., mail to an unqualified username, or to username at mailname 
(matt at peopledog.homenet in this case).

In part the issue is confusing directions:

" Please enter a semicolon-separated list of recipient domains for which    │  
 │ this machine should consider itself the final destination, apart from     │  
 │ the local hostname (peopledog) and "localhost". These domains are         │  
 │ commonly called "local domains".                                          │  
 │                                                                           │  
 │ Leaving this list blank will have Exim do no local deliveries.  
"

These two paragraphs seem in contradiction.  The first suggests that the mailname and 
localhost do not need to be provided in the following prompt to obtain local delivery for 
the mailname and localhost.  Yet the latter suggests that no local delivery at all will 
happen if the field is left blank.

As it happens it appears the last paragraph is more correct.  If I leave the list blank, in 
the resulting config.autogenerated only "@:localhost" is present in MAIN_LOCAL_DOMAINS, so 
mail qualified implicitly or otherwise by the mailname is not considered local.

If I repeat the mailname at the "other destinations" prompt then local mail is delivered as 
expected.

Thanks for your work on Debian.

Matt
