I've recently tried to register another account on spamgourmet. The email address confirmation message never arrives. I have tried manually to resend it several times; nothing has arrived so far, and it's been a couple of days. All SPAM filters are off.

ISP problem on my end is unlikely as I am using the same one (amu.edu.pl), and the messages are forwarded to it instantly.

So, my question is - are there any known problems with address confirmation messages?

Let me perhaps add an additional request for clarification: is there a difference, on spamgourmet's side, between how the address confirmation message is sent, and how all other messages are forwarded? I'm asking so that I know what to bug my ISP about.
