Quite a long time ago I talked about setting envelope sender addresses so that I could send mailshots and get back any bounces in a useful way. The missing component to it was to process those bounces within my application. Here, finally, is my write up of how I did this.
After much searching I eventually found the excellent SubEtha …
I have previously written about setting envelope senders when sending email in grails and following comments made on that post I did actually get around to submitting a patch to the plugin.
However a change to that patch was suggested and before I managed to implement it, the mail plugin underwent a fairly large refactoring which meant I needed to …
I would have expected the desire to set a specific envelope sender address for mails from a web-app to be fairly common. However finding information on how to do it with the Grails mail plugin (ie Spring mail (wrappers for JavaMail)) proved much harder than I expected.

This goes against my general email preference, but even I have relented in recent times and started allowing my mail client to display HTML email (although I still never send it)!
So with this …
The Grails mail plugin is an invaluable addition to most Grails based sites - it's a rare website that doesn't need to send email. Some really useful features have been sitting on it's todo list for a while, but it still does a lot as it is.
