When it comes to sending e-mail, modern ISP's love to gather the tares while rooting up the wheat as well. In order to prevent spam, they also prevent me and others from sending a Christian newsletter to a list of about 250 subscribers. ISP's nowadays block their port 25 and let you send only a limited number of e-mails. What can I do to keep ISP's from preventing me to mail out e-mail newsletters? In order to handle the growing number of subscribers on my list I thought about using the PostCast software to turn my own computer into an smtp server, but somehow that still requires that the ISP's port 25 and 53 be open. Are there any other alternatives for sending e-mail newsletters? Thanks for your help!
