Cannot send e-mail through wingate 6.0 after Win2K upgrade

[kostas]

Hi,

We have recently changed the system where Wingate 6.0 was installed and although browsing and pop3 collection of e-mails works fine in the new PC, wingate's smtp server cannot deliver any message received from the client machines. We used exactly the same wingate version and settings with the older PC (PIII 800, Win98), where e-mail sending (and the other functions) worked without problems.
The new PC configuration where Wingate is installed is: Win2K, nforce4 chipset, Athlon 64 X2. The company has its own domain, and we use an ISP to host our mail. We use Pegasus mail as e-mail client for the computers connected to wingate. I include part of the SMTP logs for help. Could you tell us what is going wrong?

Thank you
Kostas

well from the error logs it looks like WinGate is unable to connect to the remote servers. What happens if you try a Telnet connection to send mail, from the WinGate server?

Thanks MattP for your reply. Do you mean sending mail through Telnet connection using Wingate? Could you give me more details? Mail sending however, through Outlook or Pegasus from this machine works ok (i.e. without using Wingate).

Matt, still I have the same kind of problem as this person; all internet-trafic is OK except for outgoing mail to the mail-provider from both the XP-systems;
I did a ping to the mail provider on the routing-pc and it worked OK
I did the same ping with ip-address and with the logical name:25
both didnot work, the provider could not be found
no proxy, no ssl, no socks-host is active
internal I use 192.168.0.2-6 for ip-address; the router has 192.168.0.1
I work with DNS connections
Well: I do not know anymore; by the way, I de-installed all mail-clients, such as Thunderbird, Outlook and Outlook-Express and re-installed TB as well as Outlook (hoping a hidden indication would be reset): it did not solve the problem
What would be your next suggestion?

Hi Ruud,

Could you try a telnet connection to the remote server? You would do this as follows:

From a dos prompt:
Type Telnet (enter)
Type open smtp.qbik.com 25
You should see a welcome screen:
220 smtp.qbik.com ESMTP Service ready

This shows that you've successfully connected to the mail server. Does that work from the XP clients?

[Ruud van der Made]

Matt,
Thanks, but no success; I tried the command telnet from the dos-prompt
open smtp.qbik.com 25 (and also 23) gave following message(s)

connecting with smtp.qbik.com....cannot make connection to host, on port 23: connection failed

after this I ended telnet by 'q' (quit) ; found telnet-commands with ?
this session was from a xp-home client via the wingate router, while a firefox program was active with this forum-site and POP3 mail is coming in simultaneously; really I don't understand it anymore although my 30 years ICT carreer,
regards
Ruud

hi Matt,
this evening I think I saw happen following:
my laptop is connected to the home-office-network, in which 1 pc is running Wingate.
After starting the UMTS-card, I started from it's windows the mail-client on the laptop; after being started the mail-client received all POP3 mail from the Wingate-server and not via UMTS, I detected that on the Gatekeeper-window on the wingate server where the POP3 service for the laptop was active; when I send an e-mail from the laptop it sends via the UMTS-card;
when I open a DOS prompt on the laptop and I enter your advised commands with TELNET the response is

Connecting with smtp.qbik.com...Unable to connect with host, on port 25
A systemservice which should not fail, has been failed

end of message, after this I quited telnet by q<enter>

I suppose this telnet session tried to connect via the wingate server
The UMTS-window only services a browser and an e-mail-client

regards
Ruud van der Made

Is the UMTS card a public mobile data network card, in which case it connects to an ISP?

If so, the ISP may be blocking connections on port 25 to anything other than its own mail server - quite a few ISPs do this.

Hi!
The only way to send mail through the PC hosts is to configure the e-mail clients to send mail directly to the ISP provider, i.e by passing through wingate and disabling Wingate SMTP server, as described in Wingate mail manual. We tried this and it worked, however we preferred using Wingate's own SMTP server to deliver the e-mails to the ISP. We still try to resolve that issue. As Ruud said we can't open a telnet connection to the SMTP provider through that machine. We believe that it might be necessary to register the domain name of our machine to the ISP provider, although this was not necessary for our previous Wingate server PC (due to Windows 98?). Perhaps it will be also necessary to add the user email account details in Wingate.
I would appreciate if anyone has any idea how to resolve this issue. For the time being mails are sent to the ISP provider by passing through Wingate.

In Gatekeeper, System tab, click on Email, Delivery Tab, select use Gateway in How to deliver field, enter your ISP SMTP server in the Gateway server field, if you have to authenticate with your ISP's SMTP click the button next to that field and enter your authentication details.
