This is in reference to my post on http://forums.b2evolution.net/viewtopic.php?p=57184#57184
b2evo should allow for the use of a specified SMTP server for sending out email notifications, instead of just relying on the PHP Mail() function. The problem is that some major email providers - AOL, HotMail, Yahoo - block email from certain IP address ranges (they effectively work with broadband providers to get the address ranges they use and reject email from those IPs).
This means that for anyone (like me) hosting their own servers, emails will never get through to members unless they send them through the SMTP servers of their ISP (most broadband ISPs set their SMTP servers to allow email relaying from IPs on their network).
By relying on PHP's Mail() function, this capability is available to Windows platforms (since Windows doesn't normally have an SMTP server installed) but is not available on Unix platforms.
It would be great it b2evo could support this...I might even be willing to fund the enhancement ;)
