Topic: Using external POP and SMTP severs

[Nostromo]

Can I check an external POP server from a desktop e-mail client (from a intranet PC) and use an external SMTP server?

Yes.  If you want to access your SME's SMTP server from outside the LAN, see http://www.pagefault.org/code/e-smith.shtml#securemail for details.

I access POP and SMTP servers for my internal mail (SME) and 3 other accounts, all on external hosts, and I use their smtp servers even though I could use the SME or my ISP's I just like using each accounts own smtp service.

Example:

cyrus@langs.net.au  -  Internal/External SME POP/SMTP mail.langs.net.au
username@crap.com  -  External POP/SMTP server mail.crap.com
username@example.com - External POP/SMTP server mail.example.com

And so on and so forth, I check all these accounts using Lookout (Outlook) Express and access them through our SME 5.5 U3 gateway.

Hope that clears it up a little

Just set up multiple accounts in Outlook, pointing at each ISP's mail POP/SMTP servers, as if the sme wasn't there, and remember to tick the little box that says to collect mail from each one.
You can also choose which account to send from in the From field.
You may want to send via the sme server though if your mail has problems getting delivered, some recipients may also not like your IP and block it. In that case you may have to put the address of your service providers smtp server in the Other email settings panel, in server manager.

Ok. I know configure my Outlook Express... but...  When I try to check my e-mail, Outlook says "I can't find pop.arrakis.es server". I think is a firewall problem because proxy configuration in OE is correct (IE share it and surf OK).

When I try to send e-mails I get the same message.

P.D. Sorry, I should have explained better the problem.

That's a network connection issue. I can ping pop.arrakis.es from here fine. Can you?

Thanks Bill !. The problem is solved. You put me at the solutions way.

I could ping it from SME server console, but I couldn´t from my intranet PC. No DNS are defined in my TCP/IP configuration. I added my ISP's DNS and ... it works.

Would it work using my SME Server as DNS? I'll try it tomorrow. It's too late (1:30 a.m in Spain)

Thanks a lot!

Yes. If you use your SME as a DHCP server, it will give its own IP as the DNS and WINS servers. I'm no expert on DNS, but I think the SME caches requests. If LANPC1 goes to domain.com then LANPC2 also goes to domain.com, the SME would still have the DNS cached so the request would only have to go as far as the SME, not all the way to the ISP.

You'd think it would work, but it's not working for me.

I have a 5.5 installation that's been working beautifully for months as (among other things) the mail server for our domain 'foo.net'.

For reasons I won't bore you with, we now have our SME server as mail.foo.net for our primary mail server, and our hosting provider has a box set up as mail2.foo.net as our secondary mail server.

Here's the problem: neither the SME box nor the internal machines could resolve mail2.foo.net. I added the ISP's DNS to resolv.conf, and now the SME box can resolve mail2.owenville.net, but the internal machines still cannot.

Considering the SME box and internal machines can all resolve external addresses OTHER than mail2.owenville.net, the DNS system appears to be functioning properly. I can always manually set the ISP's DNS on all the internal machines, but that seems liks a workaround for what is probably a configuration problem on the server.

Any ideas?
