Out of interest, I have a similar problem (laptop, different smtp
servers depending on ip address). Under postfix it's easy to fix -
there's a command called 'postconf' that allows you to change the config
without editing. I run a script like this regularly from crontab:
| postconf -e "defer_transports = "
| postconf -e "relayhost = "
|
| # if we're at home, send email instantly using foobar as relay
| myip=`ip a sh eth1 | grep 'inet\>' | awk '{print $2}'`
| if [ $myip = "192.168.2.1/24" ] ; then
| postconf -e "relayhost = [192.168.2.254]:25"
| postfix reload
| postfix flush
| exit 0
| fi
|
| # and so on, for different networks...
|
| # otherwise, just defer transport
| postconf -e "defer_transports = smtp"
| postfix reload
| postfix flush
