We have 21 e-mail users in a small manufacturing company. We do not have an exchange server, nor do I want to create one. Outsourcing the e-mail is acceptable by the management. I am a support/admin group of one.
E-mail communications with some of our clients is being rejected. The reason for the rejection is the e-mail originates from Verizon e-mail servers which have been identified in some Blacklists as SPAM originators. Verizon will retry the sending of the message for up to five days. This is their policy and can not be changed. It is bad for us, since we do not know for 5 days, that the mail was not received.
I need an e-mail hosting vendor that can send mail successfully and not be blocked. Also, a reduced bounce back time frame is a requirement.
It maybe necessary to include Postini as a SPAM/Virus filter. But if a site can provide Postini with the hosting that would be a plus.
I will continue research on my own besides using the feedback from this post.
