Title: Custom SMTP port for external usage
Post by: woiks on February 20, 2007, 03:09:31 PM
Hello,

ISPs enjoy blocking port 25 and leaving ability to use only ISP server for sending mail.

Here's the case. User is a traveller between EU countries, and has to change SMTP server address in Outlook/Thunderbird each time when connecting to different ISP.

Is it possible to change SME SMTP port to non-default, let's say 5252 insead of 25? Thanks.

Use  secure SMTP - SMTP/SSL on port 465. I haven't heard of many ISPs blocking that port, plus you get SMTP AUTH so your roaming users can send mail through your server.

To the point. I tried this with 4 different ISPs and it works. Thanks, gordonr.
