Topic: 7.2 Guru Advice Needed - SMTP problems.

[wkdimp]

Hi all,

Thanks for taking a look at this thread. I'm having some problems which I'll describe below... First however a little background.

I've recently had to put an installation of 7.2 on old workstation (dual processor PIII with a 512k ram) as a stopgap as the proliant I was using has died a horrible death (smoke, sparks and all). After managing to rescue most of the data (tar.gz and scp) and and emails (making duplicate mail accounts and drag dropping the mail accross) I've managed to claw my way back to internet access and mail being delivered. Now this is SLOW but the box I'm using is only a temporary measure and I hope to replace it with a nice shiny proliant in the next 14 days... however right now when email is sent it seems to look at the sme box and report that it's sending mail... then spam the server off the network as I eventually get a "<IP ADDR> not responding message". It's worth noting that I am ONLY allowing mail from inside he network and have shut off SMTP auth, all the clients seem to be correctly configured... I'm wondering if I have a major problem or could this be attributed to the crummy box I have doing the job.

Opinions and advice appreciated.

Is your SME delivering directly to recipients' email servers, or relaying through your ISP?

If you're delivering directly, does your ISP allow you to connect to remote hosts on port 25?  (test with 'telnet mail.hp.com smtp' from the SME server itself)

If you're using a smarthost, is it configured correctly?  Does it require a username and password to allow relay, or not?

Are your clients configured to relay email through the SME server or through your ISP's mail server? (the SMTP proxy in 7.x will swallow all outbound smtp traffic by default).

I've got one network running SME 7.2 with a PIII / 933MHz / 256MB machine, so I would expect your hardware to be OK.  I do have intermittent problems with incoming email (every few months) that go away if I disable spamassassin - but most of the time this system works just fine.

If you restored your sme from .tar files &c my first guess would be that something odd happened to the smtpd, qpsmtpd or domains configuration.

If none of these hints gets you going, we'll need to see the results of the following commands.  Be sure to obfuscate any sensitive information like external IP addresses or hostnames.
config show smtpd
config show qpsmtpd
db domains show
/sbin/e-smith/audittools/newrpms

Thank you very much indeed for giving me a starting point with this problem. I'll report back results and any solution I find.
