SMTP Problem.

Posted by HIGGINS, 05-17-2011, 03:09 PM
I started my hosting business with a VPS at Giga-international. With MS Outlook I couldn't send any email messages. MS Outlook said me that it can't connect to the SMTP server. Then I tried another VPS provider, Jaguarpc. The problem was the same. Then I bought a reseller hosting at Hostgator. Suprisingly, everything was fine. I could send messages. But later I thought hostgator is not so good for me and I decided to move. Now I'm at crocweb and the problem appeared again. I really can't understand anything... What is the different among these hostings? I know HostGator is one of the largest web hosting provider but I think it doesn't matter now. Could you help me? Should I install an SSL Certificate myself?

If all the settings are correct in your e-mail client (and you have authentication enabled for the outbound server), likely what you're experiencing is your ISP blocking port 25 outbound. Most providers offer an alternate port (26, for example) that you can use which is not blocked by ISP's. SSL's are usually quite simple to install yourself, most hosting providers offer a panel that allows you to add/remove the certs, if not a quick support ticket and I'm sure they can install it for you.

yes he is right you have to check providers alternate port , and it is very simple and easy way

And would an SSL solve the problem?

So to solve the problem I just need an SSL. Can an SSL certificate change the port simply?

Yup, just try port 25 or 26. Usually one of the two.

In my case, they don't work...

You need a ssl certificate to use those ports.

Your email client and the smtp server should be able to establish an SSL or TLS connection without any interaction/certificates needed on your part. The only thing to watch for is if the port your connecting to requires SSL or TLS, even then it's a click of a radio button nothing more. As elicitservers already mentioned it, it looks like your ISP is blocking outbound smtp requests. Ask your host what SMTP ports are available 25, 26 and 587 are very common.

Thanks the replies! The problem has been solved! Higgins

The issue has been resolved. It was in fact the ISP blocking port 25. The client is now using port 26 instead, without any problems.
