Mail server

If you have a dynamic IP, your mail will likely be rejected from most major mail services.

I'm not sure what the restrictions are on OOL's server, but normally mail servers have relay options for # of messages at a time and so on. You should be able to tweak it to make the OOL server happy.

When I was running my mail server, it relayed through OOL but it was only 5-6 messages at any given time.

Yea, I think my mail was rejected last time I tried running an Exchange mail server for my domain... That was when I had plain old OOL. Now I have boost, but I'm guessing it's the same... guessing it's the same for Ultra too. Can anyone confirm?

Anyone know you e-mail directly without relaying on BOOL?

If you have dynamic IP, your mail will be rejected by most servers. Has nothing to do with your level of service from OOL.

Dynamic IP addresses are blacklisted on email servers due to spam.

If you had static IP service with Boost or Ultra, you'd have a much better shot of getting everything delivered without relaying through OOL's server, assuming the DNS records correctly indicate the address as static/business related. I know in the early days of OOL static IP service, some people reported issues getting the IPs removed from the SMTP blacklists.

Yes, you can attempt to send outbound mail from your regular Boost modem via port25 to any mail server on the Internet. OOL is not holding you back once the port is open.

What is holding you back is the fact that you are in dynamic IP space, which has about as much of a chance to get mail successfully ACCEPTED at other mail servers as a snow ball has a chance to survive 5 minutes on my BBQ.

You can either relay out through mail.optonline.net, and be subject to the same hourly limits as everyone else, or sign up for the rather cheap Static-IP service, and send directly.

Relaying out via mail.optonline.net may not work for you if you have even a moderately busy MTA, or do something bad like forwarding a whole lot of mails back out to other addresses, not employing some good outbound spam filters, or accepting&bouncing any non-deliverable mail, for any reason: non-existing accounts, spam-filter-triggered, etc: Outbound junk looks like, well: junk, and CV is (rightfully, as they must ensure high deliverability of their mail for millions of customers) not very tolerant of that with their outbound mail servers.

Are you sending from your own domain, or optonline.net email address? For about $5 a month you could register a domain and get access to an smtp server at godaddy.com, 1and1.com, or another hosting service.
