Hello, I am trying to get my mail to pop using Outlook, and it continually gives an error that it cannot connect. When I view my mail log, I see this:

./popper[20253]: Unable to obtain socket and address of client: Socket operation on non-socket (88) [pop_init.c:1050]

Also I have noticed that my server doesnt seem to be listening to port 110. When I do a netstat -tunap it shows port 25, but it does not show 110. I have port 110 open on my firewall.

Linux is new to me, so any help would be greatly appreciated.

Thanks,
Jim

Don't totally understand - you're using Outlook under Linux?

No, I am running a linux server and using an outlook mail client to check my mail...

Jim

Is it just Outlook, or do all mail clients have the same problem?

I believe pop (incoming) uses 110 and smtp (outgoing) uses 25.

No, all mail clients have the same problem. I can send mail from the server no problem to any recipients that are either on or off the server. But when I try to pop the mail I get the error from Outlook:


Task 'mail.allresell.com - Sending and Receiving' reported error (0x80042108) : 'Outlook is unable to connect to your incoming (POP3) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

And


Task 'mail.allresell.com - Sending and Receiving' reported error (0x80042108) : 'Outlook is unable to connect to your incoming (POP3) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Then when I goto the server and look at the maillog, I see this:

./popper[20253]: Unable to obtain socket and address of client: Socket operation on non-socket (88) [pop_init.c:1050]

Thanks,
Jim

Could you run:

iptables -nL
and netstat -nlp

and post anything that comes back, please.

iptables -nL

Thanks,

Your iptables rules are fine, so it would appear that the POP service is either not running or isn't listening.

Can you confirm that it is running?

If I do a ps -aux I dont see it, but I dit this

/usr/sbin/popper stop
then
/usr/sbin/popper start

And did a ps -aux and it still wasnt listed.

So I am not sure if its running...

Jim

Do you have a pop server installed?

Thats what I thought qpop was....

Jim

How was it compiled - standalone or inetd. Incidentally, the manual is here: http://www.eudora.com/download/eudor...al/Qpopper.pdf

And yes, shortly after hitting submit I realised what a dumb question I posted above.

Just a thought, but you could try telnet localhost 110 on your liunx box, this will at least prove that the pop service is listening and accepting connections.

I get connection refused....


Jim

Well then, that's your answer. You're not running a pop daemon. What distro are you using? An alternative would be uw-ipopd.
