E-mail communication problems ?

I have word back from a number of TopCubans.com Members, informing me that there have been some difficulties with the reception of e-mails sent from Topcubans.com addresses. If you have not been receiving replies to your mails (I will always reply within 24 hrs), do not hesitate to re-send me your mail, informing me that you have not had a reply. The more feedback I can get from you, the more proactive I can be in resolving problems. I look forward to hearing from you.
