Open Alternative SMTP Port

Many of VPS or Deducted Server costumers are searching how to open alternative port for SMTP, becouse many of ISP are blocking 25 port so I decided to share this articles, maybe this can help you http://www.webm.in/2008/08/open-alterna ... h-postfix/

Is there an actual use for this other than sending spam?

I believe they call it "mass email marketing", it's not spam no matter what any one else tries to tell you!

I don't know about spam, I hate spam very much like every webmaster do, but this is good when you want to use some email clients (The Bat, Outlook etc) and your ISP blocking 25 port.

I'm sure that if you contacted your ISP and told them what was up they could make an exception for you. For the most part ISP's are usually willing to work with their customers to keep them happy, providing internet is getting to be a competitive business and they want every possible customer they can get/keep.

silly people with your email clients ;P
web-based email ftw imo.

Yeah, it is much easier. No matter where you are, if you've got internet access and a browser you're set. But in a business type of setting though, I'd have to say an email client is better because of the contact lists and the calender and all that shiny junk.

yea true. i agree on that point, but for a business i highly doubt the ISP would block port 25 >.<

I have a hard time believing that an ISP really blocks ports like that at all. For one thing, you are paying for the service. Second, legit businesses could possibly host their own email server (lots do). The only time I could conceivably see an ISP blocking it is if it is a residential customer with a history of not much bandwidth usage, than all of a sudden they have lots and lots of out going SMTP with little or no incoming. To me that would indicate a bot on that network that is shooting out spam.

yup.


i'm not sure how things work in other countries though
