[FX.php List] [OFF] Slow response when sending PHP email?

[Joel Shapiro]

Howdy Steve

Thanks for the additional idea.  I've never done any SMTP server setup so will probably start down the AJAX route, but it's an interesting option.  (If I come back to it, I'll let you know :)

Cheers,
-Joel

The way in which I've handled this in the past is to run a relaying SMTP server on the web host - typically with FileMaker installs clients are using IIS, so what I tend to do is set up the IIS SMTP server on that local machine (configured to only accept and relay mail from the localhost).

(I even blogged about it :).  I haven't, though, tested this in FM12.  Have you had a chance to see if adding multiple new records in FM12 is still really slow?

I've given up my earlier belief that everything has to be pure PHP, and have toyed w/ the idea of calling an FM script from the PHP to have FMS send smtp emails.  I do realize this puts an additional load on the DB server -- as opposed to on the Web server...

In that instance I've off-loaded the record creation to FileMaker, so that the site seems fast and responsive.

I understand that this way I can check for failed sending, but I generally don't want to delay things for the end user for that -- and I'd rather deal w/ them behind the scenes, on the server end.
