@Admin, thanks for your reply.
I do have another question, sorry if I bother too much.
Since your free mail server is still under issues, and since I never managed to access Webmail page through InfinityFree Cpanel, I never created any e-mail account on your mail server. I did however created Forwarders with source address forwarded to the Gmail address. In a seven day testing period I never had any issues with Forwarders to Gmail, all messages were successfully delivered. I expected to lose mail if not because of mail server issues, then because of Gmail blocking Forwarders.
My question is this: am I just lucky I had no issues for now? Is this kind of configuration something that cannot be recommended at this time?
