I did not specify an address in my account
I have access to my mailbox, and there are messages from the forum on my mail when I was active

The issue here, is the fact that the way you're trying to recover the account, isn't among the acceptable methods (those that sign a message [correctly], usually have to wait for a very long time [more than a few months]):
If you want us to recover a hacked/lost account, you need to prove that you own it. Typically, the only acceptable method of proving ownership is by signing a message (including current date and desired new email address) using a Bitcoin address or PGP key associated with the account. A Bitcoin address or PGP key is associated with the account only if the account posted the key/address, sent it in a PM, or if it is still listed in the account's profile.
I very rarely recover accounts if you can't prove ownership as described above. There are alternative ways of proving ownership, but they take too much time. If I point you to this thread, you can't prove ownership properly, and then I ignore your future PMs, this means that I'm not going to recover your account. Create a new one.
