Scalix Forums

Hello all!

I'm having a bit of a problem here. I've had a server in testing for a while, and have had a few problems along the way ( Problem 1, and Problem 2). But, I managed to smooth all those problems out, and I just now moved to using scalix as my production email server... and am now having yet another problem!

I can send mail with SWA with no problems, and I can receive mail with no problems, but when I try to send mail using outlook via smtp (not using scalix outlook connect yet) I am getting a problem where it looks like it tries to send the mail for a while, and then times out with the error message:



Here's the output of some of my troubleshooting:






It looks to me like it's not even getting the requests, but I checked my router and everything is normal, no notices that it's blocking anything that it's not supposed to. Port 25 is open and forwarding properly.

Anyone have any ideas?

Are you sending to a Scalix user or to someone else? Are you sending from your local network? If not, have you told Outlook to use AuthSMTP when sending? Can you post your smtpd.cfg file?

Thanks,

I'm trying to send from outside of the local network to a non-scalix user. I have however tried during troubleshooting to send an email to myself (obviously a scalix user) and it still will not work.

I am using Outlook without a scalix outlook connect client installed (I want it to work both with and without, so I hadn't installed it yet). I do have outlook setup to use outgoing mail authentication. This did work previously during testing, but I don't remember specifically testing this situation recently.

I have tried rebooting both this server, and the firewall / router that protects this server, but that hasn't had any effect.

Here is my smtpd.cfg


I have smtpfilter=true because I have mailscanner installed on this machine.

As of right now I can send email, but only when using SWA, not using any external clients.

Thanks again for your help...

From outside your network, you'll need to use AuthSMTP from Outlook in order to relay messages to the outside world. If you have messages in outbox waiting to be sent to outside world, it's probably blocking the messages that are being sent to the internal users. So, tell Outlook to authenticate and you'll be fine.

Thanks,

As I said, I do have "Use outgoing mail authentication" turned on already...

unless you mean something else by AuthSMTP than that.

And I have cleared out my outbox of all mail, then try to send a new message, and I still get this error.

Two things you can try. First, from your PC, open a Command Prompt and type:

telnet mail.domain.com 25

and make sure you get something back that includes: "ESMTP Scalix SMTP Relay". If not, your ISP is blocking socket 25 outbound from their network. If you do get connected, then back on your Scalix server, edit your smtpd.cfg file and add:

DEBUG_LOG=TRUE

to the bottom of the file and restart the SMTP Relay by typing:

omoff -d0 smtpd
omon smtpd

Now, try sending again and then look in the file /var/opt/scalix/tmp/smtpd.log and see what it says.

Thanks,
Rachel

The other thing to check is if you have a Cisco PIX in between you and the Scalix server.

http://www.scalix.com/community/viewtopic.php?t=2651&highlight=fixup will give you details on how to resolve that.

Well, when I try to telnet in on port 25 from my workstation, I don't get anything. When I use the router to try to connect I get the appropriate response, which means that something isn't working right, even though everything is setup right and was once working.

Anyways, this means that the problem is either with my ISP or my router, but not Scalix, so thanks for the help! I will continue troubleshooting from there!

Thanks again for all your help!

And thanks for the tip about the Pix too, as one of these that I might be setting up in the future might be behind a Pix 506e, I'll have to keep this fixup in mind!

Another problem, possibly related, but I'm not sure.

I did narrow it down to something with my ISP as the cause of the problem, when I forward port 125 on the WAN to port 25 on the LAN, everything works as it should, so, that's what I'm doing for now until the ISP office opens on Monday or Wednesday.

A problem that I'm having though, is that any mail that I receive, I'm receiving twice. At first I thought that it was because I was sending it to myself, and I was receiving the one I sent, as well as the one I received. But then I sent me an email from a different email address, and I still received it twice.

Could this be because both sendmail and Scalix are listening as shown in my first post? I read somewhere in these forums though that sendmail *needs* to be listening to the localhost though, so I didn't think twice about that, until this happened...

Any thoughts?

Another note: I just checked my mail in SWA and I did not receive duplicate mail there. The same mail that I recieved duplicates of in outlook only show up once in SWA.

Ahem... nevermind... PEBKAC...

I didn't realize that I had outlook setup to check that email address twice.. (once with my testing domain and once with the live domain... which both now point to the same server, which resulted in duplicate emails...)

Thanks again for all your help...
