[SOLVED] Can't subscribe to mailing lists

[Spiros]

I tried to subscribe to some mailing lists following the instructions here. I sent an empty email to gentoo-soc+subscribe@lists.gentoo.org and some other lists, but I didn't receive any answers. Am I doing something wrong?

It works here, did you check your spam folder to see if the response is in there?

How stupid I am! But this is the first time Gmail spam filter fails and deletes non-spam messages.
Thank you tomk.
