| We are running the latest version (4.1.4 SP1) of IF. I have the new feature in web.config set so that all email is sent immediately. I was hoping this would fix our problem, but it hasn't. Our problem? A weird one...all email is sent fine with no problem, EXCEPT to one specific domain - ptd.net If a forum user has myname@ptd.net address, none of their email goes through, and eventually expires (I get the bounce for the "noreply" email it is being sent from.) This includes their activation email, subscription emails, private messages....everything! If I manually send an email to the same email address (by using Outlook) it works fine. Even if I write an email script on the same server using Persits ASPEmail, it goes through fine. Can anyone make any suggestions how to find the problem? At this point I'm not sure if this is a forum problem, or a problem with ptd.net's email servers, or both... Thanks for any help!

This could be a number of things, as its likely they are blocking/rejecting something about the mail from the webapp. The first thing I would look into is the reverse DNS lookup of your SMTP Relay machine through which you send the email from the webapp (this may or may not be the web-server dependant on how you're configured), this is the main cause of emails being ignored (Rejected without a response). Keep me posted on the issue via James (at) InstantASP.co.uk, i'll try to help until the issue is resolved.

| According to our network guy, our reverse DNS is working fine. The server I am using to send the mail from the forum, is -not- the webserver. Any other ideas?

Is it viable for you to contact the mail admin for that domain and ask them if they have any record of the message arrival? Is their anything on your outbound mailserver (Which should be attempting to deliver the message) about what happens when it tries to deliver? THe answer will be in a log file, either the delivery attempts logged your end, or the receipt logs their end.

| James - I have some more info on this problem. If I go into the forum, and search/find a user with an email address that has the domain problem (ptd.net), if I click EMAIL and send them an email "through" the forum this way, it works - the email sends with no problem. If the email is generated from a forum function (for instance: a notice for activation, or private message notice, password reminder, etc)...it does not go through, and eventually bounces. Is there a difference in the way the forum sends email when you manually send an email to a user, and the way the forum sends email due to a function of the forum? Both myself and our network admin are really having a tough time wrapping our heads around this one. Any other ideas?

Ok, this issue will require further investigation and possibly testing based on that most recent report, as such im going to move this post to Bug-Reports Pending, and we'll work towards finding a solution or at least identifying a pottential pitfall.

| FIXED! This email problem we've found, is specific to sending in HTML format. If you change the forum settings to send in PLAIN TEXT, the problem is gone. It seems, when sending in HTML format, the code inserts what's called a "stray line" into the email (not sure where; subject, body, etc?)... But some domains do not like this stray line, and bounce the email. I've only found 3 domains that bounce the emails (and only forum generated email) but 1 of them is huge in my area, so I needed to get this working. Doesn't seem to be a big difference between HTML and PLAIN TEXT anyway.... Thanks!
