For what it is worth, I did not implement Cybian’s fix.

It looks like this bug was introduced in an intermediate version and has been corrected in the latest version. The fix list indicated that a changed that had been made cause php to process arrays incorrectly. I had a multiple-select list for users to choose recipients. I am pretty much sure that was the problem. It is working fine now. (Thanks to CF7 author for the fast turnaround!)

I should have mentioned that the form worked before the version update.

Same error message. I just updated Contact Form 7 and this may be a versioning problem. I am using different Contact Form 7 instances and simpler ones with single recipients work, but the multi-selection get your error message. I have verified the alias addresses are forwarding just fine. (See code below.)
