Making phplist able to use more than one smtp-Host

Hallo,
some time ago I posted some code in the german forum
that makes it possible to use more than one relay-host to send e-Mails
viewforum.php?f=22
I am able to send several tenthousands emails within one our without problems.
Every update of phplist i have to rebuild my code on all my phplist installations.
I think it would be possible to modify the code and put this feature in phplist without problems.
I have tried to clearly arrange the code on my own website.

If there are any questions, or improvements, i will be glad to develop this feature.
