Post subject:  Setting up mail with Citadel
Hi all,

I just got a new Debian server set up running Apache, ejabberd, and some other stuff. I've got some experience rolling my own Linux server, but one thing that has always thrown me for a loop is setting up email.

I got Citadel installed and working and I have my user account set up, but for some reason it's not working 100%. I can send mail FROM my server, and receive it elsewhere, but I cannot send mail TO my server and have it show up anywhere.

On a (semi?) related note, I also cannot send mail via PHP. (For example, I have a contact form on my web site that's just supposed to relay me an email, and it is not working right now.)

Any ideas on any of these would be most appreciated!

EDIT: Another potentially important piece of information is that I get this every time I start the Citadel server.

Code:

Most likely you have another smtpd daemon running on port 25, stop it. lsof -n -i tcp

It appears that incoming email wasn't working due to two things: not giving it enough time (presumably for DNS to start working), and an overly aggressive spam filter. Both of these have been resolved, and mail is coming through now.

Additionally, after restarting the server, I no longer get the Citadel error I posted above.

However there is still one thing that is not working, and that is being able to send mail from PHP scripts. The contact form on my web site still returns an error when I attempt to send a message through it. Once I get that resolved, it looks like I'm all set!
