Title: Cant get or send mail, please help
Post by: msm3333 on November 15, 2004, 05:45:01 PM

Hi there!

I have installed the current version of sme with the clam av and cd-utils. everything works fine except sending and receiving mails.
I disabled the smpt proxy as told in the readme. I can ping my pop and smtp servers from the sme console directly but not from a workstation. Outlook says in cannot connect to the servers. But it works fine when the workstation is connected directliy over modem to the internet. Internet always works fine.

any ideas?

Thanks a lot

Hi,

Does the how-to says who the author is. Maybe you can contact him/her for specific problems on that specific contrib / how-to. Next to the info you probably will get in return, I'm sure the author would appreciate your feedback!

Thanks for the answer, but I do not think this is an specific problem of the clam how-to or the cd-utils how-to. I also had these problems before.

In the meantime I discovered that I cannot access FTP either. So if someone could just check my iptables? Perhaps the problem is in there....

Thanks

Hi,

Are there any custom template/fragments in '/etc/e-smith/custom-templates/etc/rc.d/init.d/masq/' ?

Hi!

directory does not exist. there ist nothing in 'templates-custom' folder.

A summary what works and what not.
Internet works from workstation also from sme (currently posting from workstation)
Ping only from sme direct to all servers and workstations. But absolutely no ping possible from workstation to any external ip or domain.
No ftp access from workstation
No smtp or pop access from workstation...

Hi.

It sounds like your LAN interface may not be working.  What does ifconfig report when logged in as root?

I hope you can find something....
Interesting ist, that LAN ist working everywhere. I can also send pings from server to workstation and back.

@RequestedDeletion

I tried both. custom-templates does not exist, templates-custom and templates-user-custom ist empty.

SME Server in server/gateway mode connected through ISDN-2 right?

Title: Cant get or send mail, please help
Post by: msm3333 on November 17, 2004, 10:59:45 AM

yes, private server and gateway mode, dialup over internal pci isdn card.
