If so, there might be an alternative solution. Exim allows forwarding through .forward file and can use pipe the emails to the shell. So if the symlink for some reason doesn't work, you might be able to capture the emails to an alternative file within your public_html space.

Yeah, Cpanel + Exim here :)

Paul, I'd like you to do a little test for me. Send several test emails from the vB diagnostics in the admin panel. Send them to bogus83y4ds (something not likely to be a real email) @ aol, comcast and hotmail, and show me the full content of the bounce file afterward, including the attachments (by PM if you prefer).

The header you showed will not be picked up by vBouncer since it's not RFC compliant, I think. Exim maybe re-writing them. If AOL, Comcast and hotmail result are in the same format, then Exim on your server might be intefering, since those ISP's do send (most of the time) RFC compliant non-delivery.

Sure - I'll PM you the results.

vBouncer 0.4 now works as a plugin, without code changes. (Thanks to Paul M)

To upgrade from 0.2 or 0.3, simply delete the old plugin and replace with the new one.

Thanks tamarian!

I am also on cPanel/Exim. Will be upgrading my server to a new box this month, but I anticipate that will be the same as I believe this is core cPanel behaviour on mail handling -- I don't think it is an option?

I will gladly help with testing as well. Just let me know what you would like done.

Well, with a few bits of suitably placed sticky tape - I have a working system on cpanel / exim. I think tamarian will be producing an update later.

A better solution, IMHO, is to use the dot-forward file method (a feature available on all these mail packages, including Exim) to directly pipe the file to another in the public_html area. I'm still looking for the correct format, but if anyone knows, please share.

Another problem with Exim, is re-writing the headers for the bounced files, which will be missed by the current log collector. I'll release an updated version to capture those.

Does the CPanel/Exim show an option to forward to a file?

The PHP restriction you speak of, would it happen to be open_basedir?

I use this extensivly across my enviroment.

All you have to do is add a single path to the directory block of the vBouncer files that allows php to access the path to the spool file.

If it isnt open_basedir, im not sure :)

I suspect CPanel might be chrooting the seperate systems, but I'm not sure, since I don't use it. But I can try to override the php.ini to see if that helps.

I do my modifications for each virtual site on my system in httpd.conf (using php_admin_value so that it cant be overridden by .htaccess).

Something like the following will allow PHP scripts to access /www/sitename, /tmp and /var/spool/mail (and outside of these paths will result in an error):

Code:

<Directory /www/sitename>

php_admin_value open_basedir "/www/sitename:/tmp:/var/spool/mail/"

</Directory>

Now, you'd have to be careful, and probably put subscriber_notify in its own directory.

Oh, and this wont help you if you're in a chroot enviroment :)
