I keep getting blocked by Spamhuas.org claiming I am sending spam emails. After researching the problem it looks like my ISP, verizon wireless (for my phone) or ? has port 25 open that allows spambots or something of the sort. I need to confirm that port 25 for Thunderbird is dedicated to outgoing SMTP emails only. For some reason it is hard to find providers that know any thing about this. I hope you can help. Also, the problem started months after I put my email on my phone when I went on vacation. I read that phone providers are know for having port 25 open and not dedicated to out going emails. Verizon was not of any help. They told me to go to google which is impossible to contact. I am open to any suggestions on what I can do about this problem.
