Bug#399185: per user smarthost

[Hendrik Tews]

I use

    #for satellite and smarthost-systems
    .ifndef DCsmarthost
    DCdefault_sh = DEBCONFsmarthostDEBCONF
    DCsmarthost = ${lookup{$sender_address}lsearch{CONFDIR/smarthost_per_user}{$value}{DCdefault_sh}}
    .endif

in exim4.conf.template and a smarthost_per_user file like 

    xxx at yy.zz: smarthost.xx.zz
    yyy at web.de: smtp.web.de::587

Bye,

Hendrik
